‘SNL’ bigs grieve

FOUR “SNL” legends got together Wednesday to remember a fifth, Page Six has learned. Chris Rock, Jimmy Fallon, David Spade and Colin Quinn had an impromptu dinner at Lure Fishbar in Soho after learning of the death of Norm Macdonald, and were overheard sharing stories about the legendary “Weekend Update” host. Macdonald died this week at 61 after a private nine-year battle with cancer. Fallon and Quinn are both fellow vets of the “Weekend Update” desk, with Quinn doing the job solo from 1998 to 2000, and the “Tonight Show” host taking the reins alongside Tina Fey from 2000 to 2004.
