There was a fad sweeping the post-War American - the tent theater! I had no idea. In Warrensville Heights that meant the establishment of the venerable MUSICARNIVAL in 1954.
The mast-and-cable tent structure remained year-round (next to Thistledown racetrack) but only in the temperature months would the tent go up, providing cover for musical acts and originally produced productions for a potential 1,500 patrons (when it originally opened - this number would grow to 2,500 in later years) seated in the round.
The first production, Oklahoma! opened on June 25, 1954.
Sunday afternoon jazz concerts were very popular.
