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 Lagoon Opera House opened in 1968, presenting summer theater shows such as "Joseph And The Amazing Technicolor Dreamcoat", "A Funny Thing Happened On The Way To The Forum", and other Broadway hits.1 The theater is part of the Lagoon amusement park, but has not been used in recent years. Most of Lagoon's entertainment shows are presented in the Music USA Theatre and the Carousel Theatre, both of which are newer and more open than the Lagoon Opera House.
