I agree about Kaye Ballard as Mrs. Lovett. She would have rocked.
I would have loved to see Bernadette as Norma Desmond. They could have re-imagined the role. Norma as a former jazz-baby, instead of a tragedienne. Though, you don't get much re-imagining in Lloyd-Webber shows. She would have sung the hell out of the role though.
The comment about Angela Lansbury in "Follies" reminds me of a bit in Ethan Mordden's "Buddies". In it, he's in a leather bar and sees these two tough looking guys talking. He wanders over and hears one say to the other, "Angela could play Phyllis and Barbara Cook could be Sally..."
