Morgan Wallen is out. Jason Aldean is in. That's the word on the headliner situation for "ACM Lifting Lives: LIVE concert" in The Colony on Wednesday, May 10.

Wallen had gotten top billing on "ACM Lifting Lives LIVE: Morgan Wallen & Friends," a fundraiser at Topgolf in The Colony benefiting Lifting Lives, the philanthropic partner of the Academy of Country Music.

But on Tuesday, Wallen posted to social media a video explaining that doctors had put him on vocal rest and he'd be canceling shows for six weeks - including his ACM-related appearances.

The 58th Academy of Country Music Awards are taking place at The Star in Frisco on Thursday, May 11; Wallen also was to perform on the show.

According to Country Now, Aldean - reigning ACM Entertainer of the Decade - was tapped as a last-minute replacement for Wallen at the sold-out benefit concert the night before the big awards show. Other performers include ACM Songwriter of the Year HARDY, reigning ACM New Female Artist and Song of the Year winner Lainey Wilson, ERNEST, Bailey Zimmerman, and DJ 13lackbeard.

The concert will follow the Topgolf Tee-Off and Rock On Fundraiser, presented by VGT by Aristocrat Gaming, taking place earlier in the day; the concert is ticketed separately from the golf tournament.

Just what does Lifting Lives do? According to a release, "in addition to distributing more than $4 million to date through its Covid Relief Fund, ACM Lifting Lives provides critical support through the Diane Holcomb Emergency Relief Fund, significant annual commitments to Vanderbilt Children’s Hospital, Music Health Alliance, and the Ryan Seacrest Foundation, and individual grants to organizations that reach communities all across America."

The ACM Awards will be free to stream live for a global audience across more than 240 countries and territories exclusively on Prime Video and the Amazon Music channel on Twitch (it'll also stream for free the next day on Amazon Freevee).The show gets started 6 pm Thursday, May 11 at the Ford Center at The Star in Frisco. There are still a limited number of tickets remaining (starting around $400) via SeatGeek, organizers say.

The Awards are being preceded by "ACM Awards Week," an entire slate of prelude parties, including:

• ACM Country Kickoff at The Star, a two-day music and entertainment festival which is open to the public, free to all fans, and does not require tickets - May 9-10.
• ACM Songs & Stories Powered by The Bluebird Cafe + NSAI, a private industry celebration of the top songwriters of the past year
• A Dolly Parton-branded pop-up shop

The 2023 edition of the Academy of Country Music Awards will mark a return to Texas for the first time since the landmark 50th ACM Awards, which took place at AT&T Stadium in Arlington in 2015.
