They said they'd never play the song again. 

They wrote it for the disaster that is Hurricane Harvey. 

Some of the lyrics are; 

“I’m dreamin’ of when I get back to Houston / I’m dreamin’ of that very special place / I’m dreamin’ of when Houston has no problems / In that city where they send you into space.” Then, the hook shares a message of encouragement: “I’m dreamin’ of when I get back to Texas / Corpus Christi, Harris County, Galveston / There’s a harmony that bonds down there in Houston / Oh Houston, you got to keep on keeping on.”
