Of the above, very few might fit the bill. Most are from traditional singers and, while accompaniment is not impossible in a few of those cases, guitar and fiddle is vanishingly unlikely. Of the commercial recordings made by male Revival performers named above, the only one I know to have used only fiddle (actually, two) and guitar was Jock Tamson's Bairns. Norman Kennedy and Andy Hunter have both recorded the song; but both, I think, unaccompanied. Ian F Benzie might be a possible; I don't know what instrumentation he used, but there was almost certainly a guitar at any rate. He has a rougher singing voice than Rod Paterson of the Bairns, if that's any help.
