The parade starts here. Well, actually this is the finale of the Showboat Majestic’s 2012 summer season, a production of Meredith Willson’s 1957 Tony Award-winning show about a fast-talking salesman who sells a town on creating a boys’ band — despite his ignorance of music — and gets caught when he becomes enamored of the local librarian.The Music Man has a great score, from “Seventy-Six Trombones” to “Till There Was You” (which The Beatles recorded in 1964, the only Broadway tune in their repertoire). Director Ed Cohen and choreographer Dee Anne Bryll, who know their way around a musical, are co-staging this one, and they’ve recruited an excellent song-and-dance man, Dan Doerger, to play Harold Hill. It’s a funny, heartfelt show about small-town America — a perfect vehicle for the historic Showboat. At the Public Landing through Sept. 30. Wednesday-Saturday. $17-$18. 513-241-6550, cincinnatilandmarkproductions.com.
