If anyone knows who did it - who recorded it? Etc.. please let us know!
(Having just played it again, I should just re-iterate that it is quite rude, and I'm not agreeing with the words that are sung... just having to say that again as I bet there's someone that still misses the funny side of it, and takes massive offence!)
Update from Annie
Not surprisingly some of my friends sent me this too - I wondered why lots of people had been searching Google looking for London Underground spoof song.
It's top must have been done in response to the ridiculous frurore about Jerry Springer The Opera. Well done to whoever did it.
