I'm 74 minutes in. Dan Aykroyd gained a lot of weight. Emma Stone is really talented. Jack Nicholson hit exactly the right note. Paul McCartney sounded awful singing a Beatles song and then pretty good singing Maybe I'm Amazed. Bradley Cooper is surprisingly funny. I didn't realize how much I missed Jane Curtin and Laraine Newman, but it doesn't compare to how much I miss Gilda Radner and John Belushi.
I can't wait for Bill Murray to show up.
EDIT: Martin Short is killing it. Chris Rock dealing. Miley Cyrus seems to be singing 50 Ways to Leave Your Lover, which is a solid homage. If she had been born in 1945 she coulda been something amazing. What a voice.
John Goodman is amazing. Actually the whole Seinfeld q&a. Sarah Palin.
EDIT2: God damn it whose idea was it to give Kanye more screentime than anyone else? When you've got Bill Murray and Paul Simon in the fucking building? All Keith Richards got to do was introduce Paul McCartney. That's just an insult.
EDIT3: Mr. Bill!
