Are you kidding me? LaChiusa and Sondheim don't write to sell tickets? That's completely absurd. If they weren't writing to sell tickets why wouldn't they just spend their own money to produce their own shows and not charge anybody to see them? Sondheim certainly could with his share of the West Side Story records.
Stephen Sondheim is and will always be a Broadway Baby. He might not write a show with the express of hope of making extraordinary sums of money but he does write to sell tickets. Sondheim writes for an audience, not himself. If he wrote for himself he wouldn't do the rewrite directors have asked him to do. If he wrote for himself he wouldn'tve changed anything to fit Angela Lansbury's voice or Glynis Johns voice.
Stephen Sondheim is a Broadway Baby who would love nothing more than to have people buy tickets to see his shows.
BSoBW2: I punched Sondheim in the face after I saw Wicked and said, "Why couldn't you write like that!?"
