It's not often in this life that you get to see someone who has EGOT'd (that's someone who's won an Emmy, a Grammy, an Oscar, and a Tony, for those who don't watch 30 Rock) performing live on stage. Hell, there's only a few of them alive, and Rita Moreno, at the age of 80 and still dancing, is one of them. Berkeley Rep artistic director Tony Taccone spent several years trying to persuade Moreno — a Berkeley resident who's appeared twice before at the Rep, in 2004's Master Class and in 2006's The Glass Menagerie — to collaborate with him on an autobiographical show. Moreno finally relented, and that show, Life Without Makeup, had its world premiere Wednesday to a sold-out audience. The show was at turns funny, moving, exhilarating, and inspiring, not the least of which was because Moreno is as limber and probably twice as candid as most women half her age.
