 Every episode of seasons one and four through seven utilized a single theme song for every episode; however, the entire second season and part of season three used various instrumental themes composed by Ray Colcord (who also composed the incidental music used between scenes and commercial breaks throughout the show's run).This practice ended with "The Last Temptation of Cory" (season 3, episode 9) as one of the cycled themes became the sole opening title music for the rest of that season.The final theme, written and performed by Phil Rosenthal, of the band Twenty Cent Crush remained for seasons five through seven, though the visuals changed from seasons 5 to 6 to include Trina McGee-Davis (when she moved from recurring cast member in season 5 to series regular cast member in season 6) and Maitland Ward (who was added as a regular cast member in season 6).
