I've never heard any suggestion of his using any other name . . leastways not during the last 20 years or so. So if he wants to be Les Barker I reckon we should leave it a that . .He's done some wonderful political satirical songs, too. (He once turned up at a June Tabor gig with a new one, taught it to her in the interval and she performed it in the second half . .)
He's a great guy, and seems rather shy off-stage.
