Crew Cuts, The
The song Sh-Boom was originally recorded early in 1954 by The Chords. But it was the version by Canadian group The Crew Cuts (released later the same year) which attracted the attention of the record-buying public.
The recording has often been viewed as the first notable move away from the middle-of-the-road sound to something resembling rock 'n' roll.
In the US it is also generally considered the first rock 'n' roll record ever to hit #1. And it didn't just hit the top - it stayed there for over two months.
