Rolling Stones guitarist Keith Richards has apologised to Mick Jagger for derogatory comments he made about the lead singer in his 2010 memoir “Life”, which caused a rift within the band. In comments reported by Rolling Stone magazine, the two rock'n'roll veterans agreed it was time to move on. Fans will be relieved to see them burying the hatchet, as the row had threatened to undermine plans to celebrate the Rolling Stones' 50th anniversary this year and to go on another world tour. “Looking back at any career you are bound to recall both the highs and the lows,” Jagger was quoted as saying. “In the 1980s for instance Keith and I were not communicating very well. “I got very involved with the business side of the Stones, mainly because I felt no one else was interested, but it's plain now from the book that Keith felt excluded, which is a pity. Time I reckon to move on.”
