Scottish singer and weaver Norman Kennedy in the 1970s recorded a fine waulking song to a fine bouncy version of the Kishmul's Galley tune and similar theme. If Hugh Roberton as indicated above claims he wrote the lyric wholecloth, then the Gaels turned it back towards the original purpose. Spooky.
Hang on - is this the same Hugh Roberton who claims to MCPS that he wrote Coulter's Candy [which was documented in the 1880s, with a Robert Coultart sweet maker and seller as the composer]?
Hugh's been at it a long time, then.
