CLEVELAND, Ohio - Aimee Mann won a Grammy for Best Folk Album ("Mental Illness") tonight, but she wasn't celebrating at the big event. She was right here in Cleveland, performing at Music Box Supper Club.

The stop was part of her tour in support of the album, her first full-length solo release in five years. Of course, she couldn't take the stage without a playful mention of tonight's award.

To start the night, she joined her supporting act, Jonathan Coulton, for a few songs. Coulton's album "Solid State" was also up for a Grammy for Best Recording Package under the art direction of Gail Marowitz. The award ultimately went to Father John Misty's "Pure Comedy (Deluxe Edition)" and Magin Diaz's "El Orisha De La Rosa."

As Mann joked to the audience, "People liked Father John Misty's package a little better than yours."

The performers weren't going to let things go without having a little fun during Coulton's set:

Aimee Mann: Did you tell the people that you were nominated for a Grammy for your package?

Jonathan Coulton: I did not. [Audience laughter]

Aimee Mann: His package was fantastic. I don't know if you've seen it. I've seen it. I was heavily involved with it.

Jonathan Coulton: Well, you had a lot of advice about my package when we were working on it. Yeah, it's a pretty good package. I'm very happy with my package. It's an honor just to be nominated. As it turns out--

Aimee Mann: People liked Father John Misty's package a little better than yours.

Jonathan Coulton: Father John Misty has a better package than I do. I knew that going in.

Audience: Aimee, congratulations!

Jonathan Coulton: Congratulations to Aimee Mann, who is a Grammy Award-winning artist!

Aimee Mann: Thank you very much. I was nominated for the folk category. And I went on Twitter, which is always a mistake. I'm sorry to take up your show time.

Jonathan Coulton: No, no, I'll cut out a couple of songs. That's fine.

Aimee Mann: The first tweet that I read was, "I don't really like sad, slow, depressing music, and you know, the Cat Stevens record was more my jam, but congratulations." [Laughs] Isn't that kind of a f-- you?

Jonathan Coulton: That's a very strange way for that person to spend their time. I feel like maybe it was Cat Stevens? A second account he uses to congratulate the people that beat him at various contests for various prizes? Writing to reviewers? "I thought your review of Cat Stevens' record was unfair." That sort of thing. So, maybe we should do some songs.

Aimee Mann: Literally one clap.

Mann later took the stage with longtime band member and producer of "Mental Illness," Paul Bryan, on bass.

Aimee Mann: As stated before, I do have a new record out that just won a Grammy. Let's hear it for Paul Bryan, who produced the record. He did a f--ing great job. I'm going to play a bunch of songs from that record. It's full of "sad, slow, depressing songs" if you haven't heard it.

She also brought up Coulton during her own set and talked about how the two worked together on co-writing several songs on "Mental Illness."

Aimee Mann: Not many people know that as well as being the internet, funny, nerdy songwriter that he's known for, he also has this folky, fingerpick-y, John Denver-y soft side. And that was the kind of record I wanted to make.

Jonathan Coulton, to audience: There's a man that appreciates softness, right there.

Aimee Mann: So I turned to Jonathan to help me co-write some songs to achieve that kind of softness.

Jonathan Coulton: Not every man can achieve the kind of softness that I can achieve. [Audience laughter]
