Forty years ago A Chorus Line was the toast of Broadway and the cast album was played at every after-rehearsal party when I was in my first year of grad school at the University of Minnesota. I was also taking a “movement” class which involved dance. I resembled a pig on stilts. Not long after, I switched to the M.F.A. in playwriting. But I love the music and the show even though I’d never make it through the first call.
