no,I am not prepared to pay to sit ,through an evening of JohnLennon songs ,different thing all together .

Indeed it is, and something nobody but you has suggested.

I dont think anyone visitng my site could seriously call me a Ewan Maccoll impersonator

Of course you aren't Dick. I was just trying to point out the absurdity of your position that anyone who sings a John Lennon song is a John Lennon impersonator and that someone who sings one John Lennon is going to spend the entire evening doing nothing else.
