I saw this at the Orpheum Theatre in Minneapolis in the summer of 1981. At the end of the first act he looked exhausted, but he had no business being on the road in a musical. He'd just gotten out of rehab and should have been home resting. Poor Meg Bussert had nothing to play off, quite clearly Des Heeley had been paid a fortune for the most hideous sets imaginable, and it was torture to sit through.
Furthermore, Tarzan the Ape Man had just been released, where he playe Bo Derek's father, and the reviews were brutal. How he survived this is anyone's guess. I agree, Run, as fast as you can, away from this disaster!
