'Is any other folk club in england blessed with so much local talent? '

There sure are 'early' - many a time I gig somewhere else other than my 'home' club (Otley) and I'm allus intrigued by the wealth of talent wher'er I go.
There are some grand residents and floor-spotters in most places - that's folk for ya!
Sometimes it seems some clubs' residents (et al) read like a who's who of the folk-scene.
Hoorah then, Otley is not alone! - cheers - Duncan
