NEW YORK (AP) - Don't expect to see all of the new cast members when "Saturday Night Live" returns this weekend for its 39th season. Except at the end when the cast is on stage saying goodbye. Lorne Michaels says "the intent is always to go slowly and not put anyone out there unless you feel they can score." Six people are joining the show. This will also be Cecily Strong's debut as co-anchor of "Weekend Update" with Seth Meyers. Michaels says Meyers will stick around at least until February and longer if he can manage to do that while replacing Jimmy Fallon on "Late Night." Tina Fey will host the premiere. Arcade Fire will be the musical guest.
