Fear not all who wondered whether this year's Grammys would be bereft of its usual wit and verve: Yesterday the WGA reached an interim agreement with the show's producers, giving its blessing to striking writers who will provide all the "Rehab"-related riffs on Amy Winehouse you crave, thereby saving the show from being forced to recycle all of last year's references to "SexyBack." Meanwhile, Kanye West's inevitable shit-fit will remain completely improvised.
