This is a promo for alsbrain.com, which is in turn a promo for Al’s Brain (a 3-D journey through the human brain with “Weird Al” Yankovic). Al’s Brain premieres at the Orange County Super Fair (July 10 – August 9, 2009) and will travel to the Puyallup Fair in September (other dates and locations to be announced).
Disclaimers: Al did not write or perform the song in this promo, and the Al’s Brain in 3-D movie (which is mostly live action) bears no resemblance at all to this video.
