I beg your pardon, Lindsay, but I wrote "Comin' Down With Old VD" in 1983 or thereabouts. I don't sing it any more, so if someone else wants to take the credit that might be OK. Of course, it's quite possible that your friend wrote a different one, by convergent evolution. Mine is still in the DT, with mostly correct words (that's the Digital Tradition, which is part of the Mudcat site; see the FAQ thread if you're having difficulty locating it).

Aloha,
Mark
