Let me just throw in the usuals:
Angela Lansbury in "A Little Night Music"
Leslie Kritzer in "Funny Girl"
OK, those are out of the way.
I know it's playing right how, but I'd love to see a revival of GYPSY in the years to come with Tonya Pinkins as Rose, but I doubt that would ever happen commercially.
Raul Esparza or Brian Stokes Mitchell with Anne Hathaway in "Carnival"
Some people paint, some people sew, I meddle.
