What do you think of Mick Jagger's treatment of the theme song?

For the most part, I like it. I think his vocals suit the mood of the song (Strange Game?). However, I don't like when he gets all falsetto in the non-verbal parts. Wish they'd use a violin or some high string instrument or synthesizer to produce that sound. It sounds affected when Mick does it, but, again, I like his vocals throughout the rest of the song.
