ANN ARBOR A recent video posted by Ann Arbor Pioneers Theatre Guild gives meaning to the phrase the show must go on.When senior Dana Steiner learned that the groups spring production of Les Miserables was canceled, she pitched the performing-in-place idea. I am a senior at Pioneer and this would have been my last musical with my younger brother and my PTG family. To help everyone record their parts, I sent out an instruction video and sample recordings of every ensemble vocal track, Steiner said in a statement. Every cast member who wanted to participate recorded themselves singing their part a cappella while listening to the accompaniment in headphones. I got sent each video individually -- 35 total -- at the beginning of May and spent weeks editing them all together.Wed say it was a big success.
