Scott McQuarrie, a Utah County developer, approached Sandy City in 2006 about building a 2,400-seat Broadway theater southwest of City Hall. The development was named “The Proscenium”, after the Greek innovation to better frame theater performances. The announcement created a rivalry between Sandy and Salt Lake City, which had also had plans for a Broadway theater. Funding for the Proscenium dried up after the credit market tumbled in late 2008.
The Willard Opera House occupied the upper floor of Charles Harding's General Store on the east side of Main Street, across from South Center Street. The opera hall, which had a small stage with wing space, was also used for recreation and dances. The Willard Opera House was in use around 1890 and was later destroyed by fire.
