Some of country music's biggest stars are turning out for a salute to Merle Haggard at next weekend's Academy of Country Music Awards.

Miranda Lambert and George Strait will team up to perform a tribute medley of Haggard's hits during the April 6 awards ceremony, and Garth Brooks will present the singer-songwriter with the academy's Crystal Milestone Award. Songs Lambert and Strait will perform include "Tonight the Bottle Let Me Down" and "I'm a Lonesome Fugitive."

The academy also announced Friday morning that The Band Perry will open the show with their new single, "Chainsaw," Hunter Hayes will perform his song "Invisible" for a child hunger charity campaign, and Luke Bryan and Florida Georgia Line will perform "This Is How We Roll" with Nitro Circus Action Stars, an action sports troupe.

Bryan and Blake Shelton co-host the live CBS show, which kicks off at 8 p.m. ET from the MGM Grand Garden Arena in Las Vegas.
