Chalk one up for effort.  Former President Bill Clinton tried to broker a Led Zeppelin reunion concert for charity, but fell short of his goal.

The former president was enlisted to ask the British rock gods to get back together last year for the Superstorm Sandy benefit concert in New York City. He asked, they said no.

David Saltzman of the Robin Hood Foundation says he and film executive Harvey Weinstein flew to Washington to ask Clinton to make the plea. Led Zeppelin's surviving members Robert Plant, John Paul Jones and Jimmy Page were in Washington just before the Sandy concert for the Kennedy Center Honors.

Following the death of drummer John Bonham in 1980, Led Zeppelin fell into a state of retirement.  A highly-watched reunion of the three remaining members occurred during the 1985 Live Aid concert.  Since that time, the group has made sporadic forays into performing together - on an on and off basis.  Their last public performance together was in 2007.
