It notably features the band's last performance with long-term drummer Keith Moon, filmed at Shepperton Studios in May 1978, three months before his death.

In 1975, he approached Pete Townshend, the Who's principal composer and lead guitarist, about compiling a collection of film clips to provide a historical reference for the band's fans.

When Stein and his film editor, Ed Rothkowitz, previewed a 17-minute compilation of clips from their US television appearances to the band and their wives, they could hardly believe the reaction.

The film crew then spent five days chronicling the daily life of drummer Keith Moon at his Malibu, California, home, including his 31st birthday party.

Finally, Stein attempted on several occasions to record performances of songs that were not covered by the archival footage, particularly "Baba O'Riley" and "Won't Get Fooled Again".

All of the band members except Townshend had seen a rough cut of the film just a week before, and, after Moon's death, they were determined not to change anything.

With the collection of material that he included, Stein attempted to create not a linear, chronological documentary but "a celluloid rock 'n' roll revival meeting" and "a hair-raising rollercoaster ride" that was worthy of the band's reputation.

While Harty delves into the background of the members' lives, Moon again steals the show as he rips off Townshend's shirt sleeve and then promptly strips down to his underwear.

Moon, according to Daltrey, was deeply shocked by how much he had changed physically in just 15 years, "from a young good-looking boy to a spitting image of Robert Newton".

[citation needed] In 2003, a DVD edition of the film was released in an expanded package with booklet and slipcase designed by Richard Evans.
