Legendary rocker Mick Jagger gets "jealous" when Keith Richards works with other people, and admits he did feel "disloyal" going solo.
The 71-year-old guitarist thinks part of the reason the group toured again in 2013 was after 72-year-old Jagger found out her was recording a solo album.
'I started [the record] when we were in hibernation, in 2007-8, so there's been no time pressure.
''All that's important is when it comes out, it comes out right," he told MOJO magazine.
''I have a feeling that when Mick found out about it, he said, 'Let's get the Stones working again.'
''He doesn't particularly like to work with me all the time, but he doesn't want me to work with anyone else, either. He's a bit jealous in that way," he added.
Richards admits he felt "disloyal" working on Crosseyed Heart, his third solo LP, but revealed he enjoyed the experience.
''It's funny because there's one part of you saying, 'You're being disloyal.'
''Then you get all the other Stones thinking, 'You're crazy, why do you need to go out and do that?'
''And I didn't really need to do it, I just enjoyed doing it.
''It's an interesting way to work, just me and Steve [Jordan], which makes it fairly cheap. There's none of the logistics involved in getting a whole band together, and after a while it started to fall into a nice groove.''
