Do I like this? No. It looks like she's wearing a hammock. But the bangs and the macrame suggest to me that she was going for an homage both to Joni and to the 70s, so I can at least UNDERSTAND it even if I wish she looked better.

Tom Hanks and Rita Wilson

Rita ALSO looks like she's feeling her inner flower child, but in a way I like aesthetically much, much better.

Jon Hamm

Did he just wake up?

No seriously, is that bedhead? Or hat head?

This is REALLY good on him. The undershirt is a little undercooked, though.

Seal

I am not super into this black and blue combo. It's very jarring.

But he changed into a longer-line black coat for the performance, which I appreciate, but... are those jeans? He looks nice though and as if he's just trying to meld into the vocals.

We're in a time in LA where it can still be like 85 degrees during the day but it'll plunge quickly to 63 at night, so BRING OUT YOUR VELVET.

Diana Krall

"Noted," says Diana Krall.

She changed for her performance into something glitzier, although I kind of like the suit better. I wonder if it would've gotten too hot under the lights?

James Taylor

James also popped by to perform, straight from... a fishing trip?

Brandi Carlile

Brandi snazzed it up bigtime. That's how it's done, James! I don't have to LOVE it to appreciate that she clearly put in some time.

Brandi Carlile

I keep wanting to tuck in that shirt, though. Also: I would've LOVED to hear hear take on "Both Sides Now," also. Maybe her voice is too ... powerful is the wrong word, but you probably know what I'm getting at here. But still. She's got the grit.

Emmylou Harris

I never noticed before how much she looks like Morena Baccarin, or vice versa maybe, so I guess we know who to cast in a biopic.

Rufus Wainwright

And while we're at it, he can be played by Jeffrey Dean Morgan.

Rufus Wainwright

Rufus brought a lot of costume changes.

Here, he is giving me less Jeffrey Dean Morgan than Bearded Jason Bateman With Crazy Eyes. I am also not a fan of the sandals, but maybe we're gonna have to just go with this Dress For Her Era idea.

Norah Jones

I was JUST wondering whatever happened to Norah Jones. I'm glad she's still out and about; her voice to me is synonymous with hot chocolate by the fire and a gentle rom-com on my TV.

Kris Kristofferson

Hi Kris! This all seems fairly standard.

Chaka Khan

AND THEN THIS. READER, ARE THOSE MESH FRINGED PANTS? Oh, Chaka. I feel for you, and I think I love you. I needed that outfit today.

Joni Mitchell

Happy birthday, Joni!
