Yes, I've been scouring the web for tune and dance notations. The Round is a folk club at Cambridge University. They have 'the dots' and dance notes for lot of Playford dances. Of course dances can have different versions according to how they are reconstructed and adapted. And tunes have variations of notes and of key (listen to a random bunch of strangers playing the 3rd section of Horses Brawl - ouch!)
