The skits they were in were pretty good. I especially got a kick out of the threesomes song. Lady Gaga's music/dance numbers were a bit of a WTF for me. Call me old fashioned, but IMHO when a person has a great voice (and knows how to use it) there's no need to don a black vinyl leotard with fishnets and a headdress which looks like it can pick up 986 satellite channels just to sing a ballad. And black vinyl is not a good enough look for Gaga for her to have done all her song & dance numbers in it. Silver and/or lamé would have given some variety. Or even white vinyl.
I think SNL's audio staff is going to hear it from her, because her hand mike and her head mike cut out a lot during two of the numbers.
Bottom line is I liked them both more than I expected to. And I like Lady G's voice enough to look up some of her tunes. I'll skip the videos, though. :-)
