There's nobody here but men, men, men, men ...
I think that's from a monty python tune (I'm certain it's something that
was played on the Dr. Demento Show).

Not from Python. Oddly enough from a 1977 Martin Mull album, "I'm Everyone
I Ever Loved". Most People don't know it, but Martin has a considerable
musical talent, and is a very accomplished painter as well. Mull's albums
mix music and comedy in a style that is all his own. The music is all
original. The 1978 album "Sex and Violins" is a beautifully composed and
fully orchestrated album of catchy songs with bizarre lyrics. Any of his
recorded material is worth a listen if you like to hear music mixed with
bone-dry comedy. Good stuff.
