I once taped a song titled 'Singing the booze' from an LP by Alastair McDonald. Maybe he is also the writer, but I don't know. The accent beats me and I can't get even a start of a decent transcription. Maybe someone knows it and can help. The chorus starts like that:

MPs, Scottish MPs, you time's now up, gentlemen, please (to the tune: Bring back my bonnie to me)
