Ahhh - That was it! Besses o'th' Barn brass band brought it back. Not the John Willie Lees song, Raggy. Definitely a Mike Canavan one with the chorus

"Well some works at the Junction
And some works at the Jam
But they all join up in t'chorus
For the Middleton Junction Band"

It refers to, if I remember rightly, the rivalry between 2 factories (the Junction and the Jam - Not sure what they were) being forgotten when they got together to play with the brass band.

Now we are talking important stuff here. The rivalry between brass bands is legendary - Probably more so than football teams :-)
