Break-Up: 1980. The group dissolved immediately after the death of drummer Jon Bonham.
Reunion: The surviving members reformed for the rare special occasion in the 1980s and 1990s, but in December of 2007 they did their first full concert since the break-up at London's 02 Arena.
Duration: One night. Jimmy Page and John Paul Jones were extremely interested in a reunion, but Robert Plant had absolutely no interest. In 2008 the group rehearsed with Steven Tyler and Myler Kennedy and even began putting venues on hold for a tour, but ultimately came to their senses.
