I lived in Shetland for many years and although there is a great musical interest, there are more tunes than songs. I must say the song is unknown to me, it does sound a little improbable, but if it exists I'm sure it will turn up here.I look forward to hearing a song that links Joe Hill with fishing and the Island of Foula? If it dosen't turn up I think I will have to write one.
Baby-Faced Nelson, (the gangster) did come from the island of Bressay.
