Mick Jagger has said he regrets having waited so long to record a new Rolling Stones album.The legendary band released ‘Hackney Diamonds’ on Friday (October 20), their first studio record of new material in 18 years – by far the longest gap between releases in the band’s 60-year career.With Jagger now having turned 80, and guitarist Keith Richards set to join him in December, the singer has been speaking to The Guardian, where he was asked whether he regrets the length of time between releases.“Yeah, kind of,” he said. “That I wasn’t cracking the whip. Keith keeps saying in interviews, ‘When Mick’s ready to do a record, I’ll do it.’ I went, OK? If that’s all I have to say, then great! We’d got into this groove of going on big tours.
