Outside of the obvious influence of the small furry ones from Wimbledon, Ashley Hutchings is probably the closest thing to an influence I have.
Steeleye Span, Fairport Convention, The Etchingham Steam Band, various versions of The Albion Band (and sometimes several at once!), Ridgeriders, Rainbow Chasers, Morris On... his list of folk band formations is enormous, you could spend 6 months just listening to his back catalogue!
He's a musical tart, just like me.
