You don't hire EGOT winner and absolute legend Rita Moreno for West Side Story and not have her sing! Moreno did some (but not all) of her own singing in the 1961 film, for which she won an Oscar for her role of Anita. This time around, she's playing Valentina, a new character for the new film who is the widow of Doc, the drugstore owner, and she gets to sing one of the musical's most iconic songs.
