Almost anything by The Rednex. They’re the ones that came out with Cotton-Eye Joe. It’s the cheesiest thing I have heard, but it always makes me smile. I think I’ll put it on.
I don’t know if I could say that it’s the happiest song ever, but Jim O’Roukes “Fuzzy Sun”, along with the rest of Halfway To a Threeway is pretty damn nifty.
I’ll second I Can See Clearly Now, Chaim, and also Good Morning Starshine from Hair, Shiny Happy People, and What a Wonderful World.
A few more:
There Must Be an Angel - Eurythmics Peace in the Valley - Sabrina Johnston I Say a Little Prayer - Aretha (or, in a pinch, Dionne) Moving on Up - M People Peace Train - Dolly Parton (I’m serious!) The Sun Does Rise - The Cranberries
Yes, the Allman Bros instrumental was indeed Jessica.
Also their song Blue Sky is a favorite of mine, Dickie Betts’ guitar just sings in that piece.
Another favorite which never fails me is Happy Jack by the Who; the combination of its tempo changes and Moon’s drumming always send my endorphins flowing.
Good call on Marley’s Three Little Birds.
“Cuz every little ting
Is gonna be allright…”
Happy song (that no one else’s mentioned):
Petula Clarke’s “Downtown”
Happy songs with creepy lyrics:
Beatles “Maxwell’s Silver Hammer” (bounciest song about a serial killer, ever!)
Hollies “Look Through Any Window” (Peeping Toms are just people!)
