The fact that Brian Jones has signed this contract on behalf of the group, shows that at this point in 1964 he was still considered to be the band leader.
The "Ready, Steady, Go" Mod Ball to which this contract refers, was televised live and according to Bill Wyman, almost turned into a riot. The Stones were expected to play on a vast revolving rostrum in the centre of an audience of 8000 fans. Getting to the stage through the crowd proved to be hazardous enough in itself Wyman recalls: ..We were instructed to mime to our first song as we walked from backstage through a corridor of security men...The moment we were announced we ran forward into the security corridor. This immediately collapsed. We then had to fight our way to the stage as best we could - while our song played to an empty rostrum! Finally on stage, Keith, pulled off-balance by some girls, disappeared head-first into the crowd; the only parts of him that could be seen in the confusion were his feet waving about. Charlie scrambled on stage with fans clinging on to each of his legs. Mick gave up miming as he was too busy playing tug-of-war with fans. During...our set we were regularly pulled off the stage into the crowd...When we finished...we were unable to leave the moving rostrum for thirty minutes...None of the other acts had reactions anything like this. Reporting in 'Melody Maker', Ray Coleman wrote: 'In mass populartity the Stones are second only to the Beatles. The [Mod Ball] line-up was strong, yet it was the Stones who caused a near-riot.'
