Garth Brooks fans who thought about waiting until later to get tickets to his Las Vegas residency might be out of luck.

Last week, the "Friends In Low Places" singer revealed that his new show Garth Brooks/Plus ONE would be in residency at The Colosseum at Caesars Palace beginning in 2023. The Ticketmaster Verified Fan presale started on Monday, and every show of Brooks' 2023 residency sold out.

"What an unbelievable day this was for us," Brooks said on his "Inside Studio G" Monday on Facebook. "Every show in '23 is pretty much…done. A whole year in one day. That's nice!"

Tickets to 27 shows were up for grabs. Fans had to register for the on sale through Ticketmaster, and as many as 60,000 couldn't get tickets.

"They had more people than they could take care of, which was very sweet for us," he said. "How do you take care of those people who weren't taken care of?"

He immediately started a dialog with Caesars Palace about the possibility of extending his residency into 2024.

"But here's the deal: If the extension happens, those people that were verified fans that did not get in – you will be first in line…for' 24…if '24 happens. It's the only way to do it."

Right now, Brooks said, it's all just talk. But if Caesars Palace says yes, he's all in.

"If '24 comes around and Caesars is sweet enough to want to do this for another year…[I] wasn't planning on it, but hey! I got nothing to do!!" he said.

When Brooks announced the residency last week, he promised fans he'd give them a new show each night and one they wouldn't forget. He plans to vary band members, incorporate occasional special guests and swap up instrumentation, background singers, or his set list to make each night a unique and memorable experience for the audience in the intimate space.

"Vegas is the place where anything goes, and The Colosseum at Caesars is the heart of Vegas," he said in a statement. "The perfect combination to present a show that will not only push the envelope, it's gonna shred it."
