The Free Mason
A very interesting jig.
The source for this tune is : Thompson’s Compleat Coll. of 200 Favourite Country Dances, vol. IV., London, 1773-1780, nr 125.
There is a very similar version (without the a minor sections) in an anonymous manuscript from the late 18th century in the Vaughan Williams Memorial Library, Yorkshire.
Yeah, it’s interesting! The last two parts are reminiscent of the Gallowglass jig, and the second part sounds a bit like the second part of Top Of Cork Road.
In the Midwest of the USA, sixty years ago or more, 6/8 tunes known as quadrilles were commonly played, and many of them had key changes between parts as this tune does.
