No, Marje, WAV is not confusing Jims Moray and Causley, (although he must be confused about a number of other things)
It was Jim Moray contributing to this thread until he left in frustration. He does, indeed, sometimes perform with synthesised instruments, although of the 5 or 6 times I saw him perform at Sidmouth 2009, he did one such gig (at the Ham Marquee) and the rest of the time sang unaccompanied or with acoustic instruments.
Jim Mo is a morris dancer. Jim C is not, as far as I know
Jim Causley did Traditional Music degree at Newcastle, Jim Moray did Music Composition degree at Birmingham Conservatoire. Both of them, though, do know and understand vastly more than most, about traditional music, however
