Here's some interesting music I found. Apparently Sun Ra worked on a children's album that was cashing in on the popular TV show "Batman and Robin" in the 1960s. The album was released under the name "The Sensational Guitars of Dan and Dave," but the band is really a combination of musicians from Sun Ra's Arkestra and Al Kooper's Blues Project
To keep licensing fees to a minimum, all the songs are based on public domain compositions like Chopin's Polonaise Op. 53, the horn theme from Tchaikovsky's Fifth Symphony and the love theme from Romeo and Juliet.
If you're not familiar with Sun Ra, he was a great pianist and arranger and ran his own band for years, which he called the "Sun Ra Arkestra." The mis-spelling is intentional. Sun Ra used to say he was from another planet. His band, the Arkestra, used to dress up in space suits, including helmets with lights on them. He claimed that he would live forever. Then he died.
My only complaint is that the song "Batmobile Wheels" is incredibly annoying. But this is a children's album after all. You might recognize the melody. Is that Tchaikovsky?
