Probably, the best book on the Rocker era.
Not many books have been written about this but Johnny Stuart does do a creditable job.
He talks about the rock 'n' roll music and how it changed and the history of the motorcycle cult.
The only flaw is the claim that the Rockers speak with their own voices - and the interviews have the flavour of the old TV interviews that had people calling the Rocker morons.
Apart from that on a historical basis well worth finding.
The book contains many photographs.
