As you are remembering Sunday's 56th annual Grammy Awards, are you thinking more about Paul McCartney and Ringo Starr, Beyonce's act, Yoko Ono dancing to McCartney's singing, or Pink's antics - or who won Artist of the Year or Album of the Year?

Industry talking heads say it's all about the performances; you can look up the other results. Other observations by AP journalists include:

PINK FLEW THROUGH THE AIR

How did Pink fly across the Staples Center during the Grammy telecast? There's a track installed in scaffolding specially designed to transport her from the center of the arena to center stage, where she joined Nate Ruess to perform "Just Give Me a Reason."

FROM YAWNS TO ...

Inside the Staples Center, the celebrity reactions to the Grammys were ranging from enthusiastic - Taylor Swift rocking out to Lorde, everyone heating up over Beyonce and Jay-Z - to downright bored. Green Day's Billie Joe Armstrong yawned during the best new artist presentation, Macklemore and Ryan Lewis sat stone-faced during Taylor Swift's performance.

TIP YOUR HAT

Pharrell Williams' hat was the fashion star of the night at the Grammy Awards - on Twitter.

The puffy brown Canadian Mountie-style fedora - or should that be phedora? - with a big brim was one of the night's boldest fashion statements.

Williams' choice of a tight red track jacket only added to the unconventional look amid tuxedos and evening gowns worn by other attendees. Like Prince's cane, Pharrell's hat had its own Twitter handle within minutes of Williams' first appearance on the broadcast, and companies like Gain and Arby's were trying to horn in on the attention.

Williams won producer of the year Sunday, his fourth Grammy.
