#Pyromania40 Facts for 40 Years! | "Where did those Union Jack shirts come from?" Def Leppard's signature Pyromania look was the Union Jack shirt and shorts, but their adoption was completely accidental. Joe remembers, "The day before the "Photograph" video...I had a budget of £25 to buy something to make this video the next day. I was down at King's Road and I think it may have been McLaren's shop Sex...I bought these plastic trousers that were too short so I had to get leg warmers...Adidas boots, handcuff belt. I've got 8 quid left, and there's this Union Jack shirt for £7.99. Outfit done. It wasn't some big plan. It was just all I had."
