Well, you see, there was a documentary on here last week which completely disagreed with that statement. According to the documentary, Jones was an extremely charismatic, technically gifted and seemingly selfish musician, whose vision for the band was basically that they became a glorified R&B cover band. They also pointed out that he had NO SONGWRITING ABILITY WHATSOVER. They seemed to suggest that the reason he left the Rolling Stones was that the Stones began to write their own songs, his own songs were rubbish, but Jagger's and Richard's were good so Loog-Oldham (sp?) turned the attention towarRAB them. Jones didn't like this, took lots of drugs to get over it, beat his girlfriend, took more drugs and was eventually so useless to the Stones that they replaced him with Mick Taylor.
