O Roll Test Orchestrion Plays Beer Barrel Polka

I like this arrangement because of the clever finale which superimposes the trills from “Stars and Stripes Forever“ over the chorus. Even though the bells and the xylophone are playing the exact same notes, the bells accentuate the single perforation trills while the reiterating xylophone brings out the sustained melody notes. If you listen carefully you'll also hear “The Pennsylvania Polka“ played as a counter melody right before the big finale.
