John.I played this in brass bands when younger.Try, www.grimethorpecolliery.com.Or any other Brass Band of note.
Ask if they have a spare conductors copy.
Yhe conductors copy gives the full score of all the instruments in the band plus a complete melody line.the peice is easy to play, but on reaching the middle eight, it is a very testing challenge to play.
I have seem the copy and played it in dance bands.But again it is part of an orc.I will ask around. Sincerely.Joe Baron
