joe henry and billy bragg sing rock island line billy sings in an american accent ,it is a good version stop talking crap,it does not prevent a good perfomance, the singers club with their proscriptive rules, they were so earnest, they seem to have forgotten that most people want to hear just a good perfomance billy bragg proves my point go on to you tube and open your ears and listen it is a good version his american accent does not ruin the performance.
long john recorded rock island line and attended the singers club, and yet you seem to think it was not him
"What made Ewan unique was his desire to share ideas and pass on opinions, information and material"of course that was generous of him ,but he was not the only one doing so ,he was not unique, for example davey graham spent a whole 12 hours showin MARTIN CARTHY DADGAD
