"BSC, only collected by Motherwell, was found only in the Glasgow area." However Palmer publishes BSC in 'Folk Songs Collected by Ralph Vaughan Williams' (no.3 p4.) and says it is the only version 'which has turned up in England'. Orignal text was 'fragmentary'so no idea how much RVW 'completed' it from Motherwell. The RVW/Palmer was the version recorded by Oyster Band which is where I first came across it - as, I suspect, did most others!
