Martie Seidel of Dixie Chicks fame made a special appearance Tuesday night for the taping a new upcoming CMT series, On the Verge. Joining Brad Paisley onstage to sing and play fiddle on his recent No. 1 hit, "He Didn't Have to Be," Seidel told the audience that in her personal experience of both being a stepparent and having a stepparent, the song had special meaning to her. Paisley, along with "Unbreakable Heart" singer Jessica Andrews, will be featured in the premiere episode of On the Verge, which follows the career development of artists on the verge of star status. The show will include performances and interviews, and will give viewers an insiders look at the making of a country star. It will premiere Wednesday, March 22 from 7-8 p.m. ET.
