Led Zeppelin formed 50 years ago, and broke up 38 years ago. In the time since the passing of drummer John Bonham in September 1980, the band has only officially reunited three times.
To celebrate the band's huge milestone, rumors swirled that they might play some shows, but those never came to pass and a coffee table photo book was released instead.
Fans have speculated that perhaps the band could tour without lead singer and reunion holdout Robert Plant. Names such as Steven Tyler, Miles Kennedy, and even Ann Wilson have come up as those who could fill Plant's shoes.
Plant has reportedly turned down several multi-million dollar offers to reunite, opting to remain a solo artist.
