Ruff and Reddy 
I can’t find this on YouTube; you’re going to have to believe I wasn’t clever enough in the mid-'60s (when I was 6 YO) to compose it, just remember it:
Load up on Mountain Dew
Ain’t nothin’ you can do
Without good ol’ Mountain Dew
Mountain Dew will do it fer you, yeah
That good ol’ Mountain Dew
Will do it fer you, YA-HOO!
I can’t prove this either, but when MD first came out, it had RED PEPPER in it :eek:
<Bill Murray> Well, that’s what I heard <BM>
“YA-HOO, Mountain Dew!” [Thumbs up!]
This one gets my vote as quite possibly the coolest theme tune ever:
I feel sorry for the poor guy at 0:48, but **I still want one of those things!!!**Yeah, good music <big thumbs-up smilie>
Can you imagine a TV theme song today at a minute 40 seconds? 
That guy must have had a big, circular bruise on his chest.
Where they street legal?
That last drawing in the clip–Col. Potter did the exact, same thing in a MASH episode. 
It’s the Pepsi generation,
comin’ at ya, goin’ strong!
Put yourself behind a Pepsi,
if you’re livin’, you belong!
You’ve got a lot to live,
And Pepsi’s got a lot to give!
You’ve got a lot to live,
And Pepsi’s got a lot to give!
Hey, meet the Swinger, Polaroid Swinger!
Hey, meet the Swinger, Polaroid Swinger!
It’s more than a camera, it’s almost alive!
It’s only nineteen dollars and ninety-five!
Swing it up (Yeah, yeah!),
take the shot (Yeah, yeah!),
count it down (Yeah, yeah!),
rip it off (Yeah, yeah!)!
It’s the radial age!
Now the world is safer on a great new tire!
It’s the radial age!
BF Goodrich boosts your mileage so much higher!
New tire from BFG,
the Radial 990!
One ride and you will see,
it rolls like nothin’ that you used to know!
It’s the radial age!
It’s the radial age!
Sorry; I cheated a little on the last one. I could only remember the first half, so I found the commercial on YouTube. 
That was actually the opening and closing themes combined, the only example of this I know.
The Untouchables, The Avengers, The Prisoner, and Hawaii Five-O (all from the '60s) round out my list of the top five TV themes ever.
Cecil and Beanie (with Dishonest John. Nya a ahhhh )
That would be a tough pick; if it had music, I loved it (the music, not necessarily the show)
Bearcats, The Magician, third season Lost In Space or anything John Williams (excepting the original** Gilligan’s Island** theme)
Oh you’ll never believe
Where those Keebler cookies come from
They’re made by little elves
in a hollow tree…
I’m stuck on Band-Aid
Cause a band-aid’s stuck on me
Honeycomb’s big yeah yeah yeah
it’s not small no no no
Honeycomb’s got a big big taste
Big big taste in a big big bite
Tater skins’ got baked potatoe appeal
Cuz they’re made with potatoes
and skins that are real
It’s Mr. Potato Head (pop)
And a bucket of parts
Buckets of fun for everyone
I truly believe that the space in my head that stores this useless crap is what kept me from greatness.
Milton the Monster?
BTW, was Wonderama syndicated? We got it off the DC station (in Balto), and I assumed it was produced there.
*Rollin’ over prairie where there ain’t no grass,
Rollin’ over mountain where there ain’t no pass.
Sittin on a board eyein’ the weather,
Prayin’ to the Lord we stay together
Side by side on the Wagon Train. *
This old chestnut popped into my head as I was driving home last night.

Join the club. 
Used to watch it on KSTP (I think) in Minneapolis every Sunday morning when I was in high school (early '70s). I know it was aimed at younger kids, but they always managed to have really good guests and lots of interesting stuff that they talked about.
I especially remember one week when their guests were an Olympic fencer and Playboy artist LeRoy Nieman. I can’t imagine a kids’ show doing that today!
Now I can’t get the Rat Patrol theme out of my mind! :o
I just watched the clip again and noticed for the first time that Ike and Bradley (I think) are riding in the Jeep in the final photo!
“Oh, you need Fluff , Fluff, Fluff,
To make a Fluffernutter…”
There’s a little hotel called the Shady Rest at the Junction (Petticoat Junction).
It’s is run by Kate, come and be her guest at the Junction (Petticoat Junction).
And there’s Uncle Joe, he’s moving kinda slow at the Junction (Petticoat Junction).
Let me help out:
“Our burgers can’t be beat 'cause we grind our own meat,
Grind, grind, grind, grind, griiiiind.
And when you drive away, a tip upon our tray
We hope to find, find, find, find, fiiind,”
We hope to find, find, find, find, fiiind!"
ETA: Beaten to it. Oh well, I’m having a great time remembering all of these.
Mr. Bubble in the tub’ll get you squeaky clean
It’s as much fun getting dirty as it is getting clean
A is for apple
J is for Jacks
Cinnamon toasted Apple Jacks
You need a good breakfast that’s a fact
Start it off with Apple Jacks
*Meet Cathy, who’s lived most everywhere
From Zanzibar to Berkeley Square,
**But Patty’s only seen the sights
A girl can see from Brooklyn Heights!
What a crazy pair!
But they’re cousins
Identical cousins all the way
One pair of matching bookends
Diff’rent as night and day**
Now Cathy adores a minuet,
The Ballet Russe, a crepe suzette,
**But Patty loves to rock’n’roll
A hotdog makes her lose control!
What a wild duet!
Still, they’re cousins,
Identical cousins, and you’ll find
They laugh alike,
They walk alike,
At times they even talk alike!
You could lose your mind
When cousins
Are two of a kind!***
*He was innocent.
Not a charge was true.
Something somthing some-um-um-um-THING!
Branded!
Something something shame.
What will you do when you’re branded?
Will you fight for your name?

As I tippy tippy toe through my garden
Where all the pretty flowers dwell
There’s a rare perfume in my garden
And I love to stand there and smell
And as I tippy tippy toe along
All the pretty flowers seem to sing this song:
I wasn’t alive when that one came out, but I did watch in on a black and white tv.
