The Warren BrothersIf you catch Tim McGraw on his Southern Voice tour this year, you may see some familiar faces in his band, the Dancehall Doctors. Brett and Brad Warren -- The Warren Brothers -- have joined Tim out on the road once again this year to write and prepare for Tim's next album.

"Tim's finishing up his record and has got a bunch of great ideas," Brett Warren tells The Boot. "He's been writing a lot lately. He's just a really talented songwriter. Me, him and Brad get together whenever we can to write. We shoot ideas back and forth. In the meantime, I said since we're already out here, you might as well stick a guitar in our hands. We love playing in the band."

Tim spotlights the brothers in the middle of his set when he sings 'Blank Sheet of Paper' and 'If You're Reading This' -- both of which were recorded by Tim and co-written by the brothers. "The three of us get up in the middle of the show with him and sing those two songs acoustically," Brett says. "We always joke around and tell a few stories. It's pretty fun. It's really cool. We love it. Brad and I are having an absolute blast."

Besides writing on the road with Tim, Lady Antebellum and Love and Theft (who will join the Southern Voice tour toward the end of April), Brett and Brad have been broadening their horizons by writing with the likes of Chris Daughtry, Hinder and Ne-Yo. "I think Brad and I have seven tracks on the next Hinder record," notes Brett. "Then me, Brad and Tim wrote with Ne-Yo which is killer! We wrote three songs with Ne-Yo in one night. He came to Tim's house. The four of us wrote, and it was amazing. He's bad to the bone!"

As far as new music from the Warren Brothers in the future, Brett says the door is always open. "We're taking it one day at a time. Right now we're enjoying being home most of the time, plus we're out here 72 shows with Tim. He's so cool, and he's such a great artist. Country music loves him, but every other genre loves him, too. Being involved with Tim and being around him is a really cool thing. He's been a good friend."

The Southern Voice tour runs through August.
