Listen to Sammy Hagar on iHeartRadio

Sammy Hagar has a lot to celebrate! The rocker turned 66 on October 13th, just weeks after releasing his latest album, Sammy & Friends, on September 24th. He partied in true Sammy style for his birthday, at his Cabo Wabo Cantina in Cabo San Lucas, Mexico.

Just before heading down there, Sammy and one of those friends, Michael Anthony, recorded the Sammy and Mikey Happy Hour, a one-hour special celebrating the release of Sammy's new album. In addition to all their lunacy and songs off the album, along with classic Van Halen, they answered emails from their fans and took phone calls from Kid Rock, Toby Keith, celebrity chef Guy Fieri and a few surprises, including business magnate Warren Buffett.
