Weezerpedia:Today's featured song/August 17, 2009
"My Brain Is Working Overtime," (originally titled "My Brain"), is a song that was demoed in 1999 by Rivers Cuomo. It was released on Alone II: The Home Recordings of Rivers Cuomo and played live during the Summer of 2000. It was an early contender for The Green Album. A reworking of the track entitled "Losing My Mind" was considered for Make Believe in 2004.
The Alone II version, which is the original demo of the song, is quite different than the SS2K version. The Alone II version is at a slower tempo, the lyrics are slightly altered and the melody is different. Also, the SS2K version has higher pitched background vocals and includes the rare use of the word "fuck," which hadn't been used in a Weezer song until this demo and hasn't been used since.
