He!He! It all adds to the interest.
I think that Cliff is a competent guitarist - but Bruce in 2003 could have been thinking about Cliff as a player nowadays - not in 1960 probably. Compared with Hank / Bruce - Cliff just wasn't in the same league as a guitarist 49 years ago. Bearing in mind the need to get recordings done in a set time (& given the number of 'breakdowns' even with the Shadows) - then I don't believe that they would have put Cliff on rhythm. Think about it. "Jet Black" (for example) has only 2 chords for rhythm & yet (it wasn't a joke) - it took over 90 attempts to nail it! (I'm not saying that Bruce's rhythm playing was the reason....I haven't heard any outtakes from that session!)
Yes - familar with Cliff playing "Apache" - & yes he did get through it - but not without mistakes & i wonder how long he had to practise to perform just that one number. Our friend and respected guitarist Colin Pryce - Jones has seen that Cliff. Even in private he's too kind to slag anyone off - but let's just say that he wasn't impressed with Cliff's rendition.
Memory - I think that I've explained pretty clearly why Bruce wouldn't recall the extra / additional rhythm. But...Cliff playing guitar on recordings would have been something that stuck in the memory much more. I have been lucky (between 1989 and 2004 especially) to be able to speak to Hank, Bruce, Brian, Jet and Tony (the latter after two Shadowmanias) at some considerable length. As I say - they were all adamant that Cliff didn't play on any Shads recordings - something I think they would have recalled.
The photograph? I think that it was probably taken during a rehearsal / run through - Cliff just filling in a bit of time on the acoustic - maybe helping to test for balance. I think that the set up was for Bruce. We know that Cliff did attend a lot of Shadows sessions - so that explains his presence. I'll stick with just putting all known knowledge together & surmising that he didn't play on the actual recordings. Of course - I can't be 100% certain.
Bests....Rob
