3:17 p.m.: Premiere Ceremony presenter Jimmy Jam offers to take Drake's Grammy for best rap/sung performance (for "Hotline Bling") home for him. "He's my neighbor, actually, so I'll make sure to drop it by his house on my way home," he quips. Drake takes home the next one too, best rap song for the same track, but songwriter Paul Jefferies keeps Jam from making two trips by accepting on his behalf.
3:30 p.m.: The Premiere Ceremony wraps up with Greg Kurstin winning producer of the year, non-classical, just after Adele took home two early awards: pop solo performance ("Hello") and pop vocal album (25). Looks like it will be a good night for the British songstress. (Update: It was.)
4:04 p.m.: Patton Oswalt didn't shy away from politics when addressing reporters backstage after his best comedy album win for Talking for Clapping. "We're living in a first-draft Monty Python sketch," he said of how to find humor in the political climate.

7:10 p.m.: Lady Gaga's jump into the crowd as she rocks out with Metallica seems staged, since it was into a mini-crowd put together in a contrived pit. The audience seems a bit stunned by the performance, but some of the well-heeled crowd -- especially men -- are vocally appreciative.

9:11 p.m.: Adele graces the press room to talk about why George Michael was so meaningful to her, how "Hello" became an instant classic, and, of course, why Beyoncé deserved album of the year for Lemonade over her own 25. "What the f--- does she have to do to win album of the year? That's how I feel," Adele tells reporters. Read the full story here.
