|Bat-Music #21 - Al Hirt - Batman Theme|
Note: I couldn't find an upload of Al Hirt's Batman theme on YouTube. However, the entire album, featuring the Green Hornet, Batman and more, is on YouTube. The whole thing is worth a listen, and it's only 26 minutes long, so it won't take up much of your time. The Batman Theme begins at 12:03. If you just want to cut to the chase, here's a link https://youtu.be/hNC-0vr1A2o?t=12m3s that begins with Batman.
