Yes, that John Lithgow. And no, there are no songs from Buckaroo Banzai. I have it on great authority that--ok, fine. Some random commenter on Defective Yeti said, "Mr. Lithgow however never ceases to entertain."
Which, if you listen to the clips on Amazon, is probably true. The man is singing to beat the oompa band, with the lyrics flying by at 100mph. If you listen to his CD's enough times, you may wish he'd cease to entertain for a few minutes. In any case, I'll leave this up until scientists prove it causes ADD.
