Fats Waller is one of the icons of the Harlem Renaissance. Follow him—or the actor playing him, of course—as he and four others pay tribute to popular black New York musicians of the 1920s and 1930s in the three-time Tony Award-winning musical “Ain’t Misbehavin’” at Delaware Theatre Company April 2-27. You’ll feel just like you’re sitting in the Cotton Club. (594-1104, delawaretheatre.org)
