Thanks Clive, I thought you were the one wot sings the 'Rose & Castle Song'.
Doug, my Kareoke comment was a bit flip. When I see 'open mike' I imagine (rightly or wrongly) a P.A. (with a mike)and a steady stream of wannabe singer song writers, probably in a wine bar somewhere. This is only my own jaundiced view, (having done the wannabe singer songwriter thing 35yrs ago).
If it's in 'Folk' setting 'singers night' is my preffered term. Lest you think I'm just a finger in the ear retro folkie, at the singers nights at our local club you can hear a wide range of musical styles & I also sing contemporary & trad songs, but I do thing that there is a lot of dross out there.
Cheers
Les
