The venerable Mark Kermode has called Richard Loncraine's film "the Citizen Kane of British Pop movies" and we're not going to argue with him.
It's been a long, long time since the film was on the big screen, and it's not always been that easy to watch it at home either.
But both those things will change next month, with a remastered version not just coming to DVD and Blu-ray on May 19, but also getting a full cinema release.

"Slade in Flame both confounded and delighted audiences when it was released in 1975, at the height of the legendary glam-rock band’s success, starring the band themselves, this was a music film like no other," reads the blurb from the BFI.
"Charting the rise and fall of a pop group at the end of the 1960s, this darkly cynical, warts-and-all portrait of a band in freefall amidst the music-industry suits who want a piece of the pie was not what anybody was expecting."
A special preview screening will be held at BFI Southbank, featuring a Q&A hosted by Kermode with not just director Richard Loncraine and actor Tom Conti but Noddy Holder himself.
