Hmmm...probably so!
George H once said that both Colin Manley and Griff Griffiths were far better guitarists than he!
Also, Colin was a Shads fan and played instrumental guitar things as well as just rock guitar solos...
Incidentally, Catswalk(AKA Cats Call) was covered as a trad jazz version by Chris Barber's Band - with Paul's encouragement- it's on YT, I happened across it the other day whilst looking for some live Chris Barber performances featuring Sister Rosetta Tharpe when she toured the UK with his band in 1957- and Marty Wilde evidently came by her goldtop Les Paul- which he gave to Big Jim Sullivan! A bit like Cliff buying the Strat for Hank a little later on!
