Sun Ra and the Blues Project

In 1966, a toy company in Newark, New Jersey released a children's record called Batman and Robin to cash in on the popular Adam West TV series of the same name. The music on the LP was credited to "The Sensational Guitars of Dan and Dale," but in fact the band was one of the greatest uncredited session combos of all time, including the core of Sun Ra's Arkestra and Al Kooper's Blues Project. To keep the music licensing fees to a minimum, all the tracks were based on public domain items like Chopin's Polonaise Op.
