ecause Public Square construction wasn’t yet completed by July 4, the Cleveland Orchestra had to postpone its annual Star-Spangled Spectacular. Tonight at 9, the free community concert finally takes place at the newly renovated Public Square. A Jumbotron program and food truck service begin at 6 p.m. The Orchestra’s festive program features Sousa marches, a group of Gershwin tunes, selections from The Sound of Music, “The Battle Hymn of the Republic,” and baritone Norman Garrett singing “Ol’ Man River” from Showboat and “Joey, Joey, Joey,” from The Most Happy Fella.
