The Hollywood Reporter has learned, Fox’s Glee has set another milestone. Star Darren Criss has become the first castmember to write original songs specifically for the Fox musical. Criss, who stars as fan favorite Blaine Anderson, wrote original song “This Time,” which is set to be one of the last songs Lea Michele’s Rachel Berry performs during Glee’s two-hour series finale on March 20. Criss teamed with friends Theo Katzman, Sam Hollander, Andrew Thielk, Eddie Montilla and Korey Richmond to write the track — set to be included in the March 6 episode.
