Mr. Monk and the T.V. Star - S2-E12
Trivia: Marcy, the obsessed fan of Brad's crime show, complains bitterly about his series changing its theme song.

Newman's vocals opened this episode as usual, but after Marcy repeats her "don't change the theme song" mantra at the end, Beal's theme was brought back to play over the closing credits. It's been used at the end a number of times since.
