Gavin DeGraw has set a date to return to the Maroon 5 / Train tour. He plans to be back on stage for the August 24th gig Columbia, Maryland. That’s a little less than two weeks away. DeGraw is still recovering from a concussion, a broken nose and some other injuries after he got beat up in New York City early Monday morning . . . then clipped by a taxi. Police still don’t have any suspects. DeGraw was alone . . . and probably a little drunk . . . when he was attacked by three guys after he left a club in Manhattan. Police don’t believe robbery was a motive in the attack, and the guys who attacked him probably didn’t even know he was famous. DeGraw himself doesn’t remember much about the incident. We’ve heard it was possible that DeGraw got into an argument with the men. But a source tells “Us Weekly”, quote, “These guys jumped him out of nowhere. It’s weird because they didn’t take anything, I think they did it for sport.”
