I have a friend who covers Tom Lehrer in piano bars, and one of the songs he covered was 'Poisoning Pigeons in the Park.' That kind of put me off Tom Lehrer.A somewhat childish sentiment, but she is only 19...
Anyway, the pigeon picture on the back of her album caught my eye, because it very closely resembles this Tom Lehrer publicity shot:
This is either quite a nice joke on Nelly's behalf, or (I'd prefer to think..) one at her expense.
Incidentally, for my money, The Remains of Tom Lehrer is one of the funniest collections that one could buy. He even did a song about the Second Vatican Council. (I might post some more about Tom anon.)
