Bethany Joy Lenz--a star of the WB television network drama "One Tree Hill"--will join Michelle Branch [ tickets ] and The Wreckers, Gavin DeGraw [ tickets ] and Tyler Hilton [ tickets ] on a tour that's being billed as "an extension of the show's storyline."

The 23-city "One Tree Hill Concert Tour" gets underway Feb. 28, and will run for more than a month.

The Wreckers--the duo of Branch and her longtime friend and Jessica Harp--will appear on all dates with Hilton and Lenz; DeGraw drops from the bill following the tour's March 11 stop in Las Vegas.

All of the acts on the tour contributed tracks to the recently issued CD "Music from the WB Television Series 'One Tree Hill'" DeGraw wrote and performed the show's theme song, "I Don't Want to Be."

Hilton--who issued his debut album, "The Tracks of ...," last September--has a recurring role on "One Tree Hill," and will portray a young Elvis Presley in the upcoming Johnny Cash biopic "Walk the Line."

In the current "One Tree Hill" storyline, Lenz' character, Haley, leaves her husband to join Chris Keller (Hilton) and The Wreckers on a concert tour. Lenz is also a musician.
