This should be a short thread. So short, it has already dropped off of page one, and I haven’t even posted it yet.
Has Floyd ever had a song with a positive, upbeat message? I’m not familiar with much pre-Meddle stuff, and I don’t know The Division Bell. Of the stuff in between, I can think of Shine On and Wish You Were Here – and those are ultimately about Syd going crazy, AFAIK. Still pretty dark.
So what of it? Any silly love songs? Have they ever told us don’t worry, be happy?
I think they created a log of crazy, funny, happy ditties in the beginning.
Arnold Layne comes to mind as well as See Emily Play.
“Pre”-Meddle stuff means, apparently, that you are familiar with Meddle? How about the lounge stylings of San Tropez, or the dirty blues of Seamus, to name two offerings? (I’ve actually heard San Tropez on the [del]Muzak[/del] radio!!!
And what Scoundrel said. Syd could be dark but he could be happy-peppy too.
Learning to Fly is probably about as close to happy or inspirational as they get in the past couple of decades. A good pile of their early work was happy in that hippy-dippy-trippy way, and it didn’t necessarily make any sense unless you partook of the appropriate substances.
The pilot’s pre-flight chatter is actually drummer Nick Mason during a flying lesson. He and David Gilmour are both pilots now.
Ever heard “Effervescing Elephant”? It sounds like a kids song.
I think Syd actually wrote that when he was a kid, which makes it even better. I’ve always kind of liked Atom Heart Mother, which isn’t exactly peppy, but not really dark either. It makes me laugh sometimes, later described by one of the members as “somewhat pompous”. ha.
And Fearless as well. Come to think of it, even Echos isn’t really that dark, just spacy. And like I said, I don’t really know the earlier stuff, except that I’ve heard Ummagumma a few times. I mostly know the 4 albums after Meddle. Dark stuff, there.
Check the lyrics again–those songs are anything but happy and funny. (Crazy, yes.) But then there are lighter things like:
The Gnome
Flaming
Bike
Candy and a Currant Bun
Spanish Piece
See Saw
Grantchester Meadows
Fat Old Sun
(the last three being musically downbeat, but lyrically cheerful)
…and the ones Ludovic mentioned.
A lot of stuff on Piper At The Gates Of Dawn is peppy, in the same way as the Beatles’ most psychedelic songs. Try the song “Bike.” 
Another vote for Bike. Here’s a link to the lyrics and a track sample.
And for the opposite, there’s “Free Four,” which is musically cheerful but lyrically kind of a downer:
The memories of a man in his old age
Are the deeds of a man in his prime.
You shuffle in the gloom of the sickroom
And talk to yourself as you die.
“Green Is the Colour” is a fairly sweet love song, though of course it’s got a downer line or two in it. Something about “Fine is the line between the hopeless and the dying”?
Oh, and Ludovic, I remember hearing “San Tropez” in the grocery store once. One of those odd moments when you suddenly notice the background music and go, “What the hell?”
The only way Candy and a Currant Bun could be more psychedelic is if they kept the original title 
Let’s Roll Another One
It’s lyrics and delivery and theme are ostensibly happy, but it’s psychedelic key and possibility to touch someone who can’t see you make it sort of creepy.
Actually, I can’t think of a song off of PatGoD that doesn’t seem to be written in some sort of psychedelic not-major not-minor key, although I’m pretty bad at identifying keys, although the allmusic listing agrees with me if their use of “chromaticism” means the same thing I am meaning here. A lot of the stuff from PatGoD comes off as creepy because of this and because of Syd’s singing, but you can still tell that they were written in the spirit of lightheartedness if they didn’t fully achieve it.
Biffy, I’d agree that Arnold Layne isn’t a very happy song because of the lyrical content, but I’d disagree about See Emily Play: I can’t really think of a song with happier lyrics. It’s just that the key doesn’t seem to agree with the lyrics and singing, (with again the caveat that I’m pretty bad at identifying key and mode,) but in Emily’s case the lyrics and delivery totally make up for this. Happiest. Song. Ever.
Wow, my take on these lyrics is so totally the opposite that I wonder if I’m being whooshed. The first verse has Emily “try[ing] but misunderstand[ing]” and living vicariously on other people’s dreams, the second verse has her crying and “gazing through trees in sorrow,” and the last verse…
Put on a gown that touches the ground,
Float on a river forever and ever, Emily…
…now maybe Syd had in mind a candy-colored psychedelic Lucy in the Sky-type boat ride, but those lines remind me of nothing so much as the famous painting of the drowned Ophelia.
as do many children when they emulate adult behavior.
okay, perhaps there is something to that.
but that’s only until “tomorrow” when she can play again.
I can’t help but visualize it as the former–the latter never even crossed my mind.
I’ve got a bike, you can ride it if you like.
It’s got a basket, a bell that rings
And things to make it look good.
I’d give it to you if I could, but I borrowed it.
You’re the kind of girl that fits in with my world.
I’ll give you anything, everything if you want things.
Syd when south before I was even born but I still miss him
Another vote for “See Emily Play” as an upbeat song. I see it as about drug experimentation. Perhaps she is maturing and no longer even plays outside, so it’s suggested she should find a way to entertain herself without leaving the house. There’s just a touch of darkness in the honesty of “You’ll lose your mind”, but it seems mainly psychedelically happy to me. The video (watchable on Youtube) is a playful romp in the park as well.
“Bike” is sort of upbeat, but there’s the slightly discordant melody, especially on “You’re the kind of girl who fits into my world”, which comes off creepy to me.
Agree with “Learning to Fly.” What about “On the Turning Away,” from the same album. This part:
Seems to convey a pretty good message. Or at least a hopeful one.
A bit off-topic, but if you want a little happy & peppy Pink Floyd, check out Polka Floyd, a band that remixes classic Floyd into a polka format (please note, I’m not associated with this band at all, but I did happen to catch a live show of theirs a couple of weekends ago, and it’s been a while since I’d seen a crowd that into a bar band).
Huh. Let me rephrase the OP:
Happy and peppy songs… by Roger?
bwahaha – reminds me of the time my Aunt bought A Collection of Great Dance Songs, which I inherited as soon as she listened to it.
