NEW YORK (AP) — The 50th anniversary celebration of “Saturday Night Live” is so big, it’s not even on Saturday. Airing Sunday and spanning three hours, the live “SNL50: The Anniversary Celebration” will assemble a dream team of stars who have helped the show become an enduring pop culture force. That includes alumni like Tina Fey and Eddie Murphy, notable hosts like Dave Chappelle and Steve Martin and at least four of the surviving original cast members. Musical guests are a whole different who’s who, with Paul McCartney, Bad Bunny, Miley Cyrus and Sabrina Carpenter among those set to appear. “SNL50: The Anniversary Celebration” airs live Sunday at 8 p.m. Eastern on NBC.
