The eighth studio album by the English rock band, originally released in August 1978.
The album was the Who's last album to feature Keith Moon as their drummer, who died three weeks after it was released. The ironic nature of the text 'Not to Be Taken Away' that was stencilled on Moon's chair on the album cover was noted by some critics.

The Deluxe 2CD set pairs the original album newly remastered plus a CD of tracks taken from the studio sessions, demo recordings and live material. The two discs are presented in an 8-panel digi-pack with a 28-page booklet.
