The answer is to put on as many singer songwriters as possible.

You get to hear new songs.

Although my club has people who sing traditional songs, I have many who sing their own songs interspersed with other songs.

An example of two different festivals without critisism and purely an observation from me..

Moor & Coast Festival Whitby - Glen allows singer songwriters (contemporary)

Whitby Folk Week - Malcolm is mainly concerned with traditional and does not encourage contemporary singer songwriters.

IMHO the Whitby Week does less for getting the youngsters into folk, verses Moor & Coast.

Bloody hell do I here the traddies jumping on their soap boxes - I hope not, becuase it is only my observation based on Ron's post above
