In 1969, Brian Jones was fired from The Rolling Stones. He had been in the band for 8 years and this left a huge hole to fill. He played many instruments, including guitar and harmonica, and also performed backup vocals on several. But as with many rock stars, he developed substance abuse issues as did fellow members of the band, which intensified existing arguments and led to Jones’s final departure from the band. He was replaced by Mick Taylor.
