What perfect timing, John!
A crowd of us got to reminiscing on this very subject at Whitby last year, and Ali has timetabled us to do a 'Singing Together' workshop/singaround at Saddleworth festival this year. See Saddleworth festival thread.

Gathering songs and information for it at the moment, so I'm sure your resource will be of great help to our aging memories :0)

Why don't you get yourself up to Saddleworth and help us out? (and Malcolm, Joan, Sal and Robyn, if not MMario and katlaughing!)

....Oh, no John, no John, no, John, No!
