23 minutes of previously unseen footage of Led Zeppelin playing live at the Pontiac Silverdome in Pontiac, Michigan, on April 30, 1977, has emerged online.
The film of the show, which saw 76,200 attendees (then a world record for a single-act show) pay $10.50 each for a ticket, has appeared on a YouTube channel dedicated to the archive the late Jim Kelly, better known as 'Speedy'. Kelly was a professional photographer and music fan who regularly shot 8mm footage of the shows he attended in the 1970s, including Van Halen, Alice Cooper, Yes, Queen, Rush and Pink Floyd.
