Didn't Oscar Brand just put out a remarkable recording of campaign songs for US presidents (Including a long song that gives a verse to each president from Washington right on up to Bill) I heard the Jefferson and Liberty cut, and the Lincoln and Liberty one (although I'm pretty familiar with that one) I believe that Grandfather's Clock also got parodied, and when I saw Jay Unger and Moly Mason, they did a couple of dance tunes written for presidents (pretty nice ones)

I think that Pete Seeger also used to sing Prescious Friend as a kind of cynical comment on Nixon?
