What's surprised me over the years is that many clubs have become dominated by singers of contemporary "folk" songs and old pop/rock songs. Back in 1970, I would have said that the future of folk clubs would depend on singers of traditional songs to keep the whole thing going. The problem with situation the other night is that it will drive many trad fans away and thereby ensuring that the balance between the old and new dips evermore towards an almost total trad wipeout.
