"There is a Funny song written by two guys called 'Flanders and Swann'"

The title of the song is A Transport of Delight; it's the first track on the At the Drop of a Hat album.

Somone has had a go at transcribing the full lyrics here, but seems to have missed the Army Lorry as a play on Annie Laurie!
(I also suspect that "Then jackal taxi drivers" should be "Them jackal taxi drivers")

Someone else has done a parody eulogising Unibus!

Unfortunately, it seems that the Great British Double-Decker Bus is now likely to be killed-off by some new EU directive? :-(

(how come the French can have double-decker trains, but we can't have double-decker buses?!)
