I'd say Johnny Kidd & The Pirates "Shakin' All Over" was the first great British rock n roll record.

Tommy was destined to become "an all-round entertainer", Cliff soon turned to insipid songs & films, Adam was never a serious rock star (his "Lonley pup in a Christmas shop" just about sums it up!), and Marty just did American covers. For my money, Vince Eager & Dickie Pride were good but never quite made it, the latter dying young.
