I guess you can find nearly every song's influences in another era  

I was listening to the 1920's network just now and was reminded so strongly of Country Joe and the Fish's hit in the 60's, "Feels Like I'm Fixin' to Die". You know the one whose chorus goes:

And it's one, two, three,
What are we fighting for ?
Don't ask me, I don't give a damn,
Next stop is Vietnam;
And it's five, six, seven,
Open up the pearly gates,
Well there ain't no time to wonder why,
Whoopee! we're all gonna die.

Well, I looked at the playlist on the radio station I was listening to and it was Lionel Hampton playing "Muskrat Ramble" from the 30's. Kid Ory wrote it in 1925, if I can read my scribbles correctly. I'm not saying the Fish intentionally too the licks from Ory and Hampton (and Louis Armstrong covered it, of course) but when you think of how few notes there are and how many songs are made, it's inevitable some would be repeated.

Do you know of any songs that are derived from bygone eras?
