Closer than you might think!
Failing any further bids, I think Sidewinder must be declared winner of this round for his remarkably near miss answer.
It's JOHN HALLAM.
Here he is with Barnes, with and without wig
Further evidence of their close association:
Have never seen Hallam, but am going to his gig on Sunday. My curiosity has been sparked by a neighbour who after 25 years has "come out" to me by revealing that he used to be a jazz musician and played guitar with Hallam. I'll post a full wig report on return!
