'Weeds' Theme Song Recorded by Dierks Bentley, Steve Martin

Dierks Bentley and Steve Martin are among the artists contributing their vocal talents to the opening credits of the popular Showtime series "Weeds." The comedy-drama series, now in its eighth and final season, features the folk song "Little Boxes," written (and originally sung in the show's first season) by Malvina Reynolds in 1962.

According to the Hollywood Reporter, Dierks' version will be heard during the opening of episode nine, while Steve Martin, on banjo and accompanied by "Weeds" cast member Kevin Nealon, will contribute a comical version of tune to episode three, which airs Sunday night (July 15). Listen to the duo perform the tune here.

Dierks, meanwhile, has been on the road nonstop. He recently traveled from Canada to St. Louis. (Check out the trek in episode 72 of his DBTV video series below.) The "5-1-5-0" singer will be in Jefferson, Wis., tonight (July 13), then travels to Normal, Ill., on Saturday and Chicago on Sunday. Keep track of his tour schedule here.
