The "As Usual" you mean is on "Ballads of Booze" by Hamish Imlach.
I can remember a bit more:
I supped a drink up like a Hoover,
As usual,
VP wine and paint remover,
As usual,
Somewhere deep inside my brain,
I seem to hear a Diesel train,
So I promise not to drink again,
As usual.

I used to play in a band which sometimes did barn dances for the Mormons. At one of these, our caller, who is actually a teetotaller, sang Whisky on a Sunday in the interval. For some reason they haven't asked us to play for them since!
