You knew it was going to be a fun night last night when a very much alive Michael Jackson appeared on stage at The Groove in Universal CityWalk. There was no official Halloween party or prizes but that did not keep some people from showing-up in costume nonetheless. Less than last year though; maybe only about 5%. It was fun and festive with the usual assortment of drink specials. Upstairs was closed so it was very crowded downstairs.
