I ahve a very vivid memory of watching Lonnie on TV ... I think it was "Putting on The Donegan" although it may have been called "The Lonnie Donegan Show". Thing is, I distinctly remember that on this particular series, his lead guitar player was Denny Wright , who was a well known London based jazz guitarist and session musician.
Denny's playing was absolutely amazing ... no disrespect to any of Lonnie's other guitarists, who were good, but Denny Wright was just different class.
I am going to work my way through all of the videos that Paul has put up on Youtube, and just wondered if any of them featured Denny Wright.
