Ian McLagan, along with singer/guitarist Steve Marriott, bass player Ronnie Lane, and drummer Kenney Jones, was a member of the British pop/rock band the Small Faces, joining in November 1965, six months after the group's formation. Before then, he had been a member of Boz & the Boz People, among other groups. McLagan's first recorded work with the Small Faces was their third single, "Sha La La La Lee," which peaked in the U.K. Top Ten in March 1966. A teenybopper success at first, the band eventually gained greater critical standing by adopting a more psychedelic style. Over the next two years, they scored further Top Ten British hits with "Hey Girl," "All or Nothing" (which hit number one), "My Mind's Eye," "Itchycoo Park" (which introduced them to American listeners, hitting the U.S. Top 40), "Tin Soldier," and "Lazy Sunday," and among their albums, Small Faces reached the Top Ten and Ogden's Nut Gone Flake hit number one.
