She was so thrilled to be singing the number with Kelsey that once the music stopped, she turned and bowed directly to him.

The Since U Been Gone singer effused that the original Frasier series was 'literally, possibly - I mean, that's a top two show for me of all time. Frasier is like one of my fav-  you have no idea, I'm freaking out right now.'

'When we got into real talks about the reboot, I had just started on Julia and was working on a musical and going to do another musical,' said David. 'I just thought: "I don’t want to be committed to a show and not be able to do stuff like this."''

Inasmuch as the show has shifted its action to Boston, 'they don’t actually need me' and 'Frasier has moved on to a new world,' David noted.

'They have new characters. And I think I’m right. It’s doing great. And the new people they have are great,' he graciously added.
