"On this day, a long, long time ago, the world was blessed with this bad a**, bass playing, singing rock 'n' roll superstar," Hagar wrote on Instagram. "Ladies and gentlemen I present to you the one. The only Mr. Michael Anthony."
Hagar is set to kick off his The Best of All Worlds tour, featuring Anthony, Joe Satriani and Jason Bonham, on July 13 in West Palm Beach, Florida. A complete list of dates can be found at redrocker.com.
