Ok. I'v managed to check a few of the sources cited, I'v even found a copy of sheet music Kenneth Alfords, Musical Switch. They all include variations on the A part, which I'm familiar with, as that's the part we sing. It's the B strain that I'v heard here for the first time here, that has got my couriosity going. I just bought a copy of the first mentioned Sound Off, when that is delivered I'll take a look at the text. Would anyone know what the source of the mudcat midi is? Joe, Max?

Thank again
