George Mason’s ‘Green Machine’ joins Lady Antebellum for surprise performance

It wasn’t until the final song before the encore at WMZQ Fest at Jiffy Lube Live that country trio Lady Antebellum revealed the “huge surprise” the group teased on social media ahead of Saturday’s show. It was a doozy. Thirty members of George Mason’s “Green Machine” pep band, along with Dr. Michael Nickens (a.k.a. Doc Nix) and associate director Jeremy Freer, helped Lady Antebellum perform their hit single “You Look Good.” ​ -D.C. Sports Bog, The Washington Post
