Fans who haven't yet gotten to see Alan Jackson's exhibit, ‘Alan Jackson: 25 Years of Keepin’ It Country,' at the Country Music Hall of Fame and Museum now have a few more months to check out the memorabilia. The exhibit, originally scheduled to close in March, will stay open until June, due to popular demand.

As part of the extension, Jackson will add his first car, a 1955 Ford Thunderbird, to the exhibit. The vehicle, which Jackson bought with his own money and restored with his father Gene, is what his wife Denise says helped convince her to go out with him.

The exhibit also features several other items, including Jackson's collection of ‘Mayberry’ memorabilia, the guitar he played at the CMA Awards when he debuted ‘Where Were You (When the World Stopped Turning),’ the Harley-Davidson motorcycle from the cover of ‘A Lot About Livin’ (and a Little ‘Bout Love),’ handwritten manuscripts of some of his classic songs and more.

“I used to think if you could have a hit or two and your career lasts three or four years, you’re very lucky. I never thought I’d have a career that lasts 25 years and is still goin’ -- I didn’t imagine all this could happen,” Jackson says. “I hope my fans are enjoying the exhibit."

The Georgia native sold out the two artist-in-residence shows he performed at the Country Music Hall of Fame last year, when the exhibit launched.

Jackson is currently crossing the country on his 25th anniversary Keepin' It Country Tour, with Jon Pardi and Brandy Clark serving as his opening acts. But while the 56-year-old has already enjoyed a quarter century in the music industry, he insists this he isn't about to ride off into the sunset.

“I don’t know what I’d retire from," he notes. "I don’t work much now."
