Sun Ra does Batman!

From the website:

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. 53, the horn theme from Tchaikovsky's Fifth Symphony and the love theme from Romeo and Juliet, and generic rock riffs. It's all instrumental, with the exception of Robin's Theme (MP3), featuring an uncredited vocalist who I hope some reader will be able identify. More info on the Italian boot reissue of this record here and here.
