We regularly play this at our Rickford session as part of a warm-up set, the first and third tunes of which are
"Harper’s Frolic" https://thesession.org/tunes/2448
and "Bonnie Kate" https://thesession.org/tunes/2452
I have transcribed this version of "Twin Sisters" from a session tape.
Blowzabella recorded a version of this,first they play in in G and then in G minor.Twin Sisters!
Re: Twin Sisters
Twin Sisters is the name given to a tune played in Maritimes Canada but it is not this tune. It is in A dorian and is more closely related to A Bag of Spuds or the A dorian version of Pigeon on the Gate. It was recorded on the Party Acadian record as well as by Gerry Robichaud.
