"It's been kind of a miracle. We did one more week [of vocal rest] and the hemorrhage went completely away. In a matter of two weeks, literally not speaking at all for two weeks. It was one of the hardest things I had to do," he said.

Keifer is convinced that thanks to the prayers of family and friends, he's doing much better. "We had a lot of people praying for me. A lot of fans and family. That's the only thing I can attribute it to because he was like, 'That's not going down. That's not going away.' And it went away."

Doctors showed Keifer what he was doing wrong vocally for the hemorrhage to appear and he's making sure he takes care of himself. "It was really hard for us to be off for two weeks because we've been going, going, going for three years," wife Shawna said. "We'd go shopping or something and then we'd separate in the store. I couldn't call him because he couldn't talk. We'd do this whistle thing like Marco Polo through the store."

The break is just what the duo needed. Back with their current single, "Everything I Shouldn't Be Thinking About," Thompson Square told Radio.com how the song came together during a writers retreat in Colorado with songwriters Brett James and David Lee Murphy. While Shawna slept in one morning, the guys had the song practically finished by the time she awoke.

"We had the guitar lick and the idea and first verse. She went over to cook and by the time she got done we had it finished up," Keifer said. "The subject matter is everything I shouldn't be thinking about so when you get three guys writing about that, it's not really hard."

He added: "Writing her verse was easy too because we were just writing about what we had hoped she was thinking about. Turned out to be a single and we're just really excited about it and it's going over great and doing well."
