Graham Jaehnig/Daily Mining Gazette The Keweenaw Symphony Orchestra performed at the Calumet Theatre this weekend, and was one of the most successful shows there in a decade.

CALUMET — The Keweenaw Symphony Orchestra performed at the Calumet Theatre on Saturday to a near sell-out audience.

“We can safely say that that was one of the biggest shows we’ve had in a long, long time,” Calumet Theatre Co. Board Chairman Dan Jamison said. “I’d say at least 10 years.”

Jamison said he did not have a final count on ticket sales, but it was over 550. The theater’s seating capacity is 625.

Jamison said the show came about as a result of an exchange of favors between the Rozsa Theater and the Calumet Theatre. Jamison and a number of Theatre members were part of a volunteer stage crew for Rosza Center’s production of My Fair Lady, he said. My Fair Lady and the symphony concert were scheduled for the same night, but parking and stages created difficulties.

“Rozsa has a big stage and a small stage,” Jamison said, “while the Calumet Theatre has a mid-sized stage. We had ‘right-sized’ the activity for the stage.”

Saturday night’s concert marked the first time in a decade that the Keweenaw Symphony Orchestra has performed at the Theatre.

Founded in 1971, the Keweenaw Symphony Orchestra is the oldest orchestra in the Upper Peninsula.

The KSO is made up of Michigan Tech students, faculty and staff, and community musicians.
