Members of the Who will go back into the studio this January to record their first album together in six years, the band’s bass guitarist John Entwistle said on Monday. Appearing at a sale of rock ‘n’ roll memorabilia at Sotheby’s auction house in London, Entwistle said the album would be released next year. The legendary band, which includes singer Roger Daltrey, guitarist Pete Townshend and drummer Kenney Jones, recorded its last album in 1982. “We won’t be going back on the road . . . but then again, who knows?” Entwistle said.
