Thanks to all that helped me with this. Here is the result:
Happy Birthday Idol
Remember that the video was amateur footage, with lousy lighting (I had to alter his exposure a LOT), auto exposure, auto-focus, etc., and no green screen. It was just a plain background in his house. However, with all the help you guys gave me, I ended up with a pretty good key and, by keyframing some of the elements of the masking tracks, was able to minimize the need for garbage masks, although I still needed to use them in a few places where the background would have otherwise come through his teeth.
Also, this was for his own private use in his home with friends and family, and he loaned me his American Idol DVD, so I think we were well within fair use of the copyrighted material. (And I did it for free, for an old friend). Since he didn't script this, I had to find reaction shots that made sense, and I also had to find sounds to mask the fact that the audio was so different between his video and the pro stuff, and also, their audio had music underneath at times. I would have loved to have had a set of soundbed CDs, but I found a few things in the ACID loops that worked OK.
