Listen to Dan + Shay on iHeartRadio

Dan + Shay took the stage at the iHeartRadio Country Festival and gave the audience their best, performing songs such as "What You Do To Me" and "19 You + Me." 

Then, they wanted the best from the crowd, and invited the entire Frank Erwin Center to sing along to "Show You Off."

The audience must have done well, because the band referred the event as a "festival and a half!"
