Definitely Arthur Brodie, front row, 4th from the left, leaning on his euphonium. To the left of him (3rd from left) is, I believe, a very young Joe Grant from Clifton Row. A fantastic cornet player who often played the solo spot outside the council offices (where the judges sat) at the miner's picnic. He is the only specs- wearing member of the colliery band I have seen. Judging from his age this photo must be early fifties. Perhaps Joan Morland might remember him as well.
Other than those two there are only two others I recognise but can't put a name to them as yet.
