Tucked away in a corner of Las Vegas's MGM Grand with wife Faith Hill by his side, Tim McGraw surveys a room filled with friends and collaborators from the past two decades. It's an eclectic group from the who's who of music: Taylor Swift and Nelly hug for a photo, Keith Urban documents the spectacle on his cell phone, and later Ne-Yo, Luke Bryan and the Lady Antebellum guys watch a basketball game in a nearby dressing room. "It's a great energy," says McGraw, 46, of the A-list performers he assembled for his two-hour TV special. "All the people in this room inspire me to press the gas harder."
