Batman theme song squeaked by actual bats

Cool? Or the most annoying sound ever? I add the latter because that’s how it was described to me. I quite like the “bats’ song” but I’m not sure about the bloody maw of the vampire bat that pops up throughout the video.

This is the work of Sándor Seuntjens. Sándor assigned digitally reduced frequencies of actual bat sounds (so we could hear them) to keys on the keyboard. He then played the famous opening music. The result? The Batman theme of the 60s as sung (or squeaked) by bats.
