Hey GSS, trust you are well.

"EFDSS started it all with dance musicians playing from the dots and using music stands "

The EFDSS may have gone around arresting songs and tunes and locking them up in CSH but the use of dots for playing dance tunes goes back before Playford and has always been a feature of playing dance tunes.

Isn't that wht some many written collections of old dance tunes have survived?
