Thanks for all that, Richard. I've been playing tunes from the Winder MSS for many years now, thanks in the first place to your efforts to disseminate them.

My own experience with the Thomas Watts MS (Derbyshire Peak District) is similar. Whoever wrote that down (and it may have been more than one person) played dance tunes and psalms, as well as a very few songs (NOT what we would generally regard as 'folk') and one or two oddities like the cello part for Handel's 'Judas Maccabaeus'. So there was an overlap between folk dance, religious, and art music.

I should probably know this already, but how many tunes are reproduced in more than one of the Winder MSS, and is there any evidence of temporal change?
