Kenny Chesney, Jerry Cantrell, Matt Sorum Rock Sammy Hagar's Birthday Bash

Sammy rocked four shows at his Cabo Wabo Cantina, performing a different set each night that included guests like Chickenfoot bandmates Michael Anthony and Joe Satriani, Matt Sorum, Kenny Chesney, Billy Duffy of The Cult, Jerry Cantrell of Alice In Chains, and Denny Carmassi of Montrose.

"Man, this is hand's down the best birthday bash yet!" wrote Hagar. "Hangin' at the beach with my family and friends, then my buddy [chef] Emeril [Legasse] cooked us an amazing dinner and we all headed to the Cabo Wabo where Kenny Chesney brought the whole band down and tore it up for 3 hours! The fans were so off the hook I just had to hit the stage and jam on a couple songs with Kenny -- and we even got Emeril on stage with us to sing back up on "I Can't Drive 55".
