I've listened again to the other recording of Silkie by Dave Burland, on Songs & Buttered Haycocks: he uses the same tune, similar to John Sinclair's, in both recordings. I take the chance to ask once again: the John Sinclair noted by Otto Andersson in 1938 and the John Sinclair recorded on Peter Kennedy's anthology Sailormen & Servingmaids (I think in 1961) are the same person?
Thanks. R
