Gavin DeGraw's Brother Joey Irritated by Alleged Morgan Wallen Chair Incident

Nashville bar owner Joey DeGraw‘s not happy about Morgan Wallen‘s alleged rooftop bar antics, ’cause while the tossed chair didn’t hit anyone … it could still ding the city’s booming nightlife scene.

Joey and his brother, singer-songwriter Gavin DeGraw, know all about Nashville’s Broadway party scene — they own one of the strip’s hot spots — and he tells TMZ … he’s annoyed Wallen allegedly chucked a chair from the 6th floor because it could’ve seriously hurt someone.

JD says he’s not worried about Morgan and his drinking — in fact, he thinks the incident might help his career — but he is worried about how it might impact tourism on Broadway, Nashville’s main attraction attraction.

To be clear, Joey says he didn’t see the alleged incident, but says chucking furniture off a roof is, obviously, a dumb choice … no matter what Morgan’s circumstances turn out to have been.
