Answering a question from ABC13's Pooja Lodhia, Brooks said the best thing about the concert here is that the audience will get to sing along to all tunes about the rodeo.
"We got a ton of them," Brooks revealed. "When you look at the setlist, you go, 'Oh, we get to play 'Beaches' here. We get to play 'Rodeo' here.'"

On Monday, Brooks gave fans a 25-minute preview behind the scenes of the new stage on Facebook Live.
Brooks says the new star-shaped stage is a performers dream.
He hasn't played the Rodeo since 1993. So, he's excited to be back in Houston to open and close the rodeo.
Brooks even brought on some fans to talk and sing with, like NASA astronaut Tracy Dyson.

He also took questions from some Houston super fans.
The country music legend said this won't be his usual show.
"They have a time restraint here because you are part of the rodeo. So, this isn't going to be the usual Garth show where we can go for two or three hours. You go on at a certain time and go off at a certain time. My hardest part is trying to fit into the segment that they give you," said Brooks.
Brooks' opening and closing concerts are sold out but some tickets are available on ticket resale sites.
