The great theater composer Stephen Sondheim loved puzzles, and when he died in 2021, he left one for his good friend, British super-producer Cameron Mackintosh. He left him an unfinished show.
The two men conceived of a revue of Sondheim's songs during the pandemic and they both began lists of tunes they wanted. But with the death of his friend, it was up to Mackintosh to make the show real.
