Whiffenpoof, if anyoine doesn't happen to know, is a parody of Kipling's "GENTLEMEN-RANKERS" (I'm told that Rudyard wasn't fond of the parody). I think that it dates back to the early 1900s.
Sandy- I don't have a date for the Cheer, cheer for Old Notre Dame parody; I suspect that it's 20th century, though it's clearly folk. If there is an American drinking song tradition, it's likely to be imbedded strongly in college songs and military service songs.
Anybody know how old The Souse Family (Drunk last night, drunk the night before..) is? And how should I handle things like SHOW ME THE WAY TO GO HOME and SWEET ADELINE?
