Colum Sands: great songs and stories and has people rolling around laughing: from N Ireland so may have to wait for a tour.
Flossie Malaviaille too, tho' the last time I saw her thought there was a wee bit TOO much talk versus song time. Does some great Piaf numbers among other things.
Quicksilver (Grant Baynham and Hilary Spencer).
Robin Laing (appeals to whisky lovers too!)
