New Warner Bros. act Trick Pony is already off to a good start. For its debut album, the country trio recorded a song with country legends Johnny Cash and Waylon Jennings. The group's first single, "Pour Me," is a clever play on words that has already cracked the Top 30 on Billboard's country singles chart. And members Heidi Newfield, Ira Dean and Keith Burns recently debuted on the Grand Ole Opry. "I was composed at the Opry while I was onstage, but as I was walking off I started to tear up," Newfield says. "That's when it really hit me that I've wanted to play that stage all my life."
