I wasn't there either, but I see from the programme that the MC was Ian Russell, so the version he sang was almost certainly the one known as the 'Noah Dale Anthem'. Noah Dale is in the upper part of the Calder Valley in West Yorkshire, and the inhabitants obviously adopted the song as their own. The tune and first verse are as in the Thomas Moore version, though I think the second and third verses are Calderdale's own.

Bob Pegg played a recording of this version during his talk at the museum last week, sung by Harry Greenwood of Midgley, and it was also sung (sorry, can't remember by whom)at the concert in the Rifle Club entitled 'Music of the Moors and Lakes"

The Noah Dale Anthem is in print in 'Songs of the Ridings' by Mary and Nigel Hudleston.
