I agree 100% that Alan Jones is an excellent bass player and was perfect for the Shadows. I enjoyed his tenure enormously. His recorded legacy is first class.
As to historical questions, they can be answered with facts where we have them. Where we don’t, a bit of guesswork is only human nature. However, this site is also historical in nature and I read some isolated comments in this thread which strayed from fact to conjecture and also touched on personal areas. On balance I thought it would be better to trim them out. I apologise to three contributors to this thread for perhaps leaving you wondering and I am more than happy to address any outstanding questions via the PM system.
Many thanks - Iain
