Since they broke up in 1980, Led Zeppelin has only performed together five times, with the fifth and as of now last time being December 10th, 2007 at London's O2 Arena. The previous four were at Live Aid in 1985, Atlantic Records' 40th anniversary celebration in 1988, Jason Bonham's wedding in 1990 and their induction into the Rock and Roll Hall of Fame in 1995. The first two were public appearances, both of which, says Jimmy Page, left the band "a little uncomfortable." So for the 2007 show, Page says their goal was to "go out there and stand up and be counted." On Monday they released Celebration Day, the entire 2007 show, on CD, vinyl, DVD and Blu-ray so you can be the judge as to whether or not they got it right.
