Luke Bryan loves the holidays with his family on the farm: 'I become Clark W. Griswold'

— -- Luke Bryan loves getting into the holiday spirit with his close-knit family at their farm in Nashville.

“I become Clark W. Griswold. I’m falling off things,” Bryan told ABC News of the beloved movie character who had 25,000 lights on his home display in National Lampoon’s "Christmas Vacation.”

“We have a big time. We’re going to get the whole family in,” he added. “Some of the family we don’t like so we try to put them way out in the barn, in the loft. I’m digging myself a holiday hole right now.”

The country music superstar caught up with “Good Morning America” from the new Opry City Stage in New York City’s Times Square, designed to mimic Nashville’s Grand Ole Opry.

“We have customized it to my own pop-up shop right here,” he said while signing autographs for his fans. “My album’s out today so we’re having fun here in Times Square. Country is coming to town.”

Bryan said when he was a little boy he “never in a million years” imagined he’d be singing country music for devoted fans in New York City.

“You ought to hear my family ask, ‘Now how do you shows up there? There are really country music fans up there?’ But yes, there really are, tons of them,” he said.

He also surprised “Good Morning America”’s Lara Spencer with a festive Christmas sweater equipped with a beer bottle opener doubling as the star-topper on the tree. “Luke, you’ve outdone yourself,” Spencer said with a laugh.
