Sorry to poop this party but The Songwainers were never the same after Ken Langsbury joined them. When they were the splendid residents at the Victory Club in Cheltenham he was the club clown who adopted a risible yokel persona, with a bravura in inverse proportion to his talent, whose groan-inducing party piece was Susannah's A Funniful Man.

Having seen him perform fairly recently I can only say that Shakespeare's description of Cleopatra:
Age cannot wither her, nor custom stale
Her infinite variety
may be exactly reversed in his case.

He was arrogant, tuneless and unable to enhance the already sub-floorspot ensemble of which he was a part.
