“Broadway’s Next Hit Musical,” an improvised musical comedy, will be at the McPherson Opera House at 7 p.m. Saturday.

“I love to book shows that involve audience participation, and this one does it in spades,” said John Holecek, opera house executive director. “Each person in the audience is asked to make up a song title and write it down on a paper slip we provide. The six performers then randomly pull song titles out of a fishbowl and make up songs to go with the titles. The audience then votes on the song they like best, and right before their eyes, the cast delivers a full-blown, improvised musical comedy based on the song.”

Tickets are available at the box office, by calling (620) 241-1952, or online at http://mcphersonoperahouse.org.
