Patti LuPone brought the house down Sunday night at the Grammys with her performance of “Don’t Cry for Me Argentina,” from Andrew Lloyd Webber’s “Evita.”

The diva originated the namesake role when Lloyd Webber’s musical debuted on Broadway in 1979.

It’s no small achievement that the Grammys scored LuPone for its Lloyd Webber tribute. Earlier this week the actress and composer ended a feud that spanned more than two decades.

24 years ago Lloyd Webber fired LuPone from the lead role of Norma Desmond in Sunset Boulevard, which she had originated in London, and replaced her with Glenn Close, who won a Tony for that Broadway performance in 1995. Thus began a two-decade-plus feud between LuPone and Webber,

But when LuPone agreed to perform at the Grammys, as part of a tribute to both Lloyd Webber and Leonard Bernstein, it indicated a possible end to the cold war. Thursday, LuPone, according to the New York Post,reportedly picked up the microphone and announced the détente, which resulted in a whole room of witnesses (who had been waiting anxiously to see what would happen) bursting into laughter. Lloyd Webber and LuPone embraced, and the rehearsal kicked off.
