Jimmy Page and Robert Plant

Pictured above is guitarist Jimmy Page (front, to the right) and lead singer Robert Plant (back) of Led Zeppelin, one of — if not the — greatest rock bands in history. This backstage photo was taken on June 10, 1977 when Zeppelin played Madison Square Garden. Led Zeppelin broke up just three years after this photo was taken, though there have been a few reunions, including one as recently as 2007. Plant was reportedly offered $200 million to go on tour with Zeppelin after that 2007 show, but shockingly turned it down. Plant and Page have feuded publicly over the years.
