According to David Saltzman of the Robin Hood Foundation, movie executive Harvey Weinstein came up with the scheme: “Weinstein had this great idea that we could enlist Bill ClintonWilliam (Bill) Jefferson ClintonAfter FBI cleared by IG report, GOP must reform itself Bill Clinton hits Trump administration policy separating immigrant families in Father's Day tweet Trump's strategy for North Korea and beyond MORE to convince Led Zeppelin to reunite to perform at the 12-12-12 concert.”

Saltzman says the 42nd president was game, telling the pair, “I really want to do this. This would be a fantastic thing. I love Led Zeppelin.”

But when Clinton approached the “Stairway to Heaven” musicians, who were being recognized at the Kennedy Center Honors last year, the answer was a big, fat no. “Bill Clinton himself asked Led Zeppelin to reunite, and they wouldn’t do it,” recalls Saltzman.

All wasn’t lost though. On the way back from the dud of a mission, Saltzman says he bumped into Rolling Stones guitarist Keith Richards in the airport and he agreed to rock out with his band at the star-studded charity concert.
