After it opened in 1870 as a rollerskating attraction, The Rink became a favorite playhouse. Situated at the site of the Elektron Building, 215 E. Berry St., The Rink was converted into a theater in 1880 and renamed The Academy of Music (also, it later came to be called The People's Theatre). In its heyday, troupes like the London Theatre Company and the American Opera Company made regular stops at The Academy, as did the Buffalo Bill/Annie Oakley extravaganza. It was during this time the custom arose of singing the national anthem at the close of each play. - See more at: http://egen.fortwayne.com/ns/projects/history/haw2.php#sthash.uhykLbDP.dpuf
