ND passed me by back then, but I was belatedly introduced to his music (by partner's son) a few years ago, & like it a lot - the non-orchestrated stuff seems quite timeless, which to me suggests a real talent, rather than a follower of musical fashion; I have heard his 'before-he-was-famous' cd, & there his debt to Bert Jansch is more in evidence, & I would characterise his music as Jansch-imbued-with-English-pastoralism, as it seems to evoke a similar feeling to eg Vaughn-Williams..I agree that Dave Evans was similarly gifted, & equally timeless, but would suggest that DE is under-appreciated, rather than ND being overly so..all goes back to Jansch, tho, IMO..
