surprise appearances from some of dave's friends. jay leno will not be there. rumors for months maybe letterman's long-time rival would show up and make one appearance on "the late show" but leno has apparently declined. i don't want to say it's officially 100% but letterman's producer makes it sound like we won't see leno. here's what rob bur net told me yesterday. >> i would love to have jay on the show. i think we all would have loved that. one last time would have been a beautiful end note to a fascinating relationship between these two guys. it didn't come to pass. that's jay's call. no hard feelings. they have to make their own decision on that. >> so no leno but maybe we'll hear from kimmel or the other late night comedians. jimmy kimmel said he encouraged people to watch letterman instead. i will have a show but go over to cbs and watch letterman instead. it's going to be a historic night. >> i'm surprised by the fixation on whether jay leno will be there. dave wasn't on jay's last show
