A traditional singer is, of course, anyone who sings. Hence Harry Cox, Louis Armstrong, Mick Jagger and Dame Kiri TeKanawa are all traditional singers. Oh yes, and Bob Dylan. This strange state of affairs has arisen because only in the field of folk music are we denied definitions - because they are oppressive and they stop people who do rock music performing in folk clubs - although, actually they don't unless the particular club has a policy - and policies are oppressive ... aren't they?
