Judy Collins, Barbara Cook, Judi Dench, Sutton Foster, Maria Friedman, Hermione Gingold, Glynis Johns, Cleo Laine, Angela Lansbury, Patti LuPone, Audra McDonald, Ethel Merman, Donna Murphy, Imelda Staunton, Barbara Streisand, Elaine Stritch … The list of irreplaceable Stephen Sondheim divas is endless—and let’s not forget Dame Edna (“He loves it when I tweak!”) Everage. Even so, Bernadette Peters has a special place in the pantheon. Her Sondheim tribute will be a night for the ages. —Matthew Gurewitsch
