I was totally pissed off about no singing things - psych outs, whatever. Those things are one of the reasons I love the show.
You don't get them when you download it from iTunes, either.
I did love the deleted scenes. They explained things that I had wondered about, like why the end of the Scary Sherry show and the whole thing with Mercedes Ruehl. I thought that whole Mercedes business was kind of funny, but kind of dumb. Once I saw the deleted scene, it all made sense.
