I know this is not an ad, but when I saw mention of the Yankee Doodle tune, I immediately thought of this one and had to post it. Believe it or not, a friend of ours sings this at sessions:

Roger Ramjet

Roger Ramjet and his Eagles
Fighting for our freedom
Fly through and in outer space
Not to join him but to beat him.

Roger Ramjet he's our man
Hero of our nation
For his adventure just be sure
And stay tuned to this station.

Come and join us all you kids
For lots of fun and laughter
As Roger Ramjet and his men
Get all the crooks they're after.

Roger Ramjet he's our man
Hero of our nation
For his adventure just be sure
And stay tuned to this station.
