Hey Kuriboh Man! I assume you mean the Avalon performances? Unfortunately I haven't seen them, but I could tell you that, from the special we got on TBS last year, George Michael was probably my favorite. The 50's manners movie one sounds like it could have a lot of potential; I remember when Mystery Science Theater 3000 did their "Shorts" collection with some old 50's movies like that and they were a riot!
I'm curious, is there anywhere online where some of these skits can be seen? I haven't checked Henson.com yet this week, so they might be there and I'm just unaware of it. Good topic though!
