Kenny Chesney will perform Friday (Oct. 12) during Sammy Hagar's 65th birthday celebration in Cabo San Lucas, Mexico. Only 500 tickets, priced at $55, are available for the show at Hagar's Cabo Wabo Cantina. Chesney first performed at Hagar's birthday bash in 2004 when they performed for almost four hours. This year's event will also feature celebrity chef Emeril Lagasse along with Michael Anthony (Van Halen), Joe Satriani (Chickenfoot), Matt Sorum (Velvet Revolver and Guns N' Roses) and Denny Carmassi (Montrose). Chesney completed his Brothers of the Sun stadium tour with Tim McGraw in August.
