Just discovered this conversation. So I will add my thoughts.
Yes I agree that Move It and Shakin All Over both definitive British and probably best R & R records made in UK. But I must point out that no matter whether you think Tommy Steel's records were weak, he was still the first to play R & R in Britain. I personally think his version of Singing the blues was better than Guy Mitchell's, but I don't want to argue the point. He wrote a couple of nice songs as well, although not R & R.
Some facts I think are true :-
Joe Brown was the guitarist used for Sounds of Fury.
Big Jim Sullivan was the lead in Marty Wildes Wildcats, although Uncle Bert did the Duane Eddy bit on Endless Sleep.
Didn't Mike Pratt and Lionel Bart write Rock With The Cavemen.
As a last thought Helen Shapiro's Walking Back To Happiness is always the one mentioned, but I always thought You Don't Know was a far superior record, but still not R & R.
I'll get my cocoa now.
