OK, here's the tune I transcribed from Paddy Graber's singing of The Arbutus CLICK HERE. And the nwc file with the first verse CLICK HERE. The end of the second phrase is a little muddled because Paddy half speaks/sings it there. But it is certainly a variant of Malcolm's tune.

I'll be seeing Paddy again at Rainy Camp around the 1st of Feb and will ask him about it then.
