Exclusive 'Life' Excerpt: Keith Richards on the Debaucherous 1972 Rolling Stones Tour

 LONDON – Rolling Stones guitarist Keith Richards describes frontman Mick Jagger as unbearable in his soon-to-be published autobiography.

Richards says he and Jagger used to be friends but have been estranged for decades. The details about his strained relationship with Jagger are spelled out in Richards' book "Life," which will be published Oct. 26.

In an interview published Friday in The Times newspaper, Richards says he has given up drugs since he required brain surgery after falling from a tree in Fiji in 2006.

He says he and Jagger are discussing another possible Stones tour despite their differences.

 The 1972 tour was known by other names – the Cocaine and Tequila Sunrise tour or the STP, Stones Touring Party. It was the beginning of the booking of whole hotel floors, with no one else allowed up, so that some of us – like me – could get privacy and security. It was the only way we could have a degree of certainty that when we decided to party, we could control the situation or at least get some warning if there was trouble.
