"Test Pattern," MuchMusic's inaugural game show in the late 1980s to early 1990s, featured Bill St. Amour on music and sound, with announcer Bill Carroll. Hosted by Dan Gallagher and produced by Sidney M. Cohen, it included Canadian musicians and used foam bricks to select topics in a points-based contest. Season one had four five-time champions who won trips, later competing for a home stereo in a "Tournament of Champions." Notably, winning a 2-slice toaster became an iconic prize. The show concluded after two seasons.
