Def Leppard are an English rock band that formed in 1977 and has a number of hit songs including "Bringing on the Heartbreak", "Photograph", "Hysteria", "Let's Get Rocked", "Rock of Ages", and of course "Pour Some Sugar on Me". They've sold over 100 million records worldwide and are one of only five bands with two original albums that sold over 10 million copies.
The band was surprisingly good live and played most of the songs listed above. It was interesting to see drummer Rick Allen drumming with only one arm.
In 1984 he lost his arm in a car accident and thought his career was over. He had engineers develop a drumset where he could use his left foot to trigger the snare drum and he relearned how to play.
