Before Luke Bryan and Dierks Bentley suit up to host the Academy of Country Music Awards on Sunday (April 2), the singers paid tribute to their country roots with a joint cover of Merle Haggard's "Ramblin' Fever" on The Late Show with Stephen Colbert.
Appropriately clad in flannel and denim, Bryan and Bentley strummed their guitars and brought their best country twang to pay tribute to the late country legend Wednesday night (March 29). As proven by their harmonies, the country stars were totally in sync on stage -- something that will serve them well when the ACMs take place just a few days after their Late Show performance.
For the second year in a row, Bentley and Bryan will partner up to host the ACM Awards, which brings Nashville's biggest names to Las Vegas. This year's show will be Bryan's fifth ACM hosting gig, while Bentley's return marks his second go around.
The pair sat down with Colbert prior to their performance to give a preview of what they have in store for their joint hosting spot this year, giving Colbert some advice for his own hosting job at the Emmys in September. "Drinking beforehand, lots," Bentley joked.
