Very little in the way of details has emerged since the Rolling Stones acknowledged that they were working on a new album, the group's first since the passing of drummer Charlie Watts. Variety broke the news that Paul McCartney accepted an invitation to play bass on the album and also brought up the possibility that Ringo Starr would play drums on it. Ringo's involvement has now been walked back by the publication, and Rolling Stone seems to have sussed out that McCartney may only appear on one song on the release.
