 Wood had contributed to some tracks on the Rolling Stones prior two albums, 1974's "It's Only Rock 'n Roll" and 1976's "Black and Blue", and joined the band full-time in 1976.With a stable line-up in place for the first time in several years, the album marked a return to basics for the Rolling Stones, unlike many of the prior albums there were few guest musicians.One notable contribution, however, does come from blues harmonica player Sugar Blue on "Miss You".
