Sammy Hagar held his fifth annual Acoustic-4-a-Cure benefit concert Tuesday night at the Fillmore in San Francisco.

This year’s show once again benefited the pediatric cancer program at UCSF Benioff Children’s Hospital, but it was also a 76th birthday party for the legendary bluesman Taj Mahal, who’s a friend of Hagar’s.

The night’s finale was an all-star jam with Hagar, Taj, Bob Weir, Kevin Cronin of REO Speedwagon, Michael Anthony, Chad Smith, Joe Satriani and Don Was. But right before Hagar brought out his friend, celebrity chef Guy Fieri, who’d baked a birthday cake to mark the occasion. 

Hagar says it was “an enlightening experience for me on so many levels… Every year I have been winging it, flying by the seat of my pants, fingers crossed and wiping the sweat from my brow at the end of each show. The fifth time was the charm for me. I discovered the magic is finding the right group of people and just letting it happen… Everyone brought something to the show, everyone participated in the complete event, wholeheartedly, and it was a friggin’ blast for all of us.”

Other highlights included:

  • A reunion of Hagar’s Chickenfoot
  • Bob Weir doing the Grateful Dead‘s “Friend of the Devil” with Kevin Cronin, along with “Only a River” and “Easy Answers”
  • Eddie Money performing a short set with his daughter Jesse
  • Taj turning in a short set that included “Corrina” and “Fishin’ Blues”
