Saw it with my son last night and we nearly peed our pants laughing.
Some really tender moments too with Levy and Catherine O'Hara, especially the rose and the non-kiss. I don't want to give too much away, but it's well worth seeing.
I think we've all encountered Bob Balaban's fussy concert organizer too.
I for one, am going to start doing some of the songs from the show without telling the audience where I got them, just to see if there are any flickers of recognition.....
