The problem is that folkies like Martin have so few chances to show what they can do on a high profile tv show. I will say again, that if Martin could have been allowed to do "Never Any Good" and show his spectacular - and at one time unique - percussive guitar style ( where he flicks his fingers on the lower strings achieving a dynamic driving sound), then he would have gained at lot of new fans. If Martin chose "Duncan and Brady" over "Broke Down Engine" then he made a mistake. I know I hold great store by Martin's percussive guitar style but it was unique to him back in the 70s and he is still is the best at it. I remember that spectacular fingerpicker Adrian Legg saying that he felt very imtimidated at the thought of following Martin after he (Martin) had let rip with his percussive guitar style. Look at it this way: Nothing Eric Clapton did on the guitar was unique. Martin's percussive style was unique; and "unique" should be treasured because it doesn't come around very often!
