Buchan & Hall and McColl & Seeger both printed 'cheer up my lads', Nigel Denver's personal pronounciation of the word notwithstanding.

The DT transcription is pretty accurate if it was made by ear, rather less so if it was copied from either book (the title is mis-spelled, for one thing). Both books print the same tune, though in Buchan & Hall it is transposed up from three flats to one, and the variations shown in McColl & Seeger are omitted.
