Whether you watch NBC's theatre-drama Smash religiously or you've never even heard of the show, you might want to tune in this week: Andrew McMahon (Something Corporate, Jack's Mannequin) will get his TV debut, or at least his music will. McMahon wrote the song "I Heard Your Voice In A Dream" which Season 2 newcomer Jimmy Collins (played by Jeremy Jordan) will perform.


You can check out a clip of the performance below, and be sure to catch the whole song during Smash tomorrow at 10 p.m. ET/9 p.m. CT.
