Pow! Bam! Batman theme tune performed by real bats

A group of musicians have used the sounds bats make to give the Caped Crusader's theme tune a makeover.

Bats produce noises that are not usually audible to humans but the group recorded the mammals in the wild and then digitally reduced the sounds to create their masterpiece.

The end result is a techno-style Batman theme tune that sits better with Adam West's 1960s camp version of the Caped Crusader than Christian Bale's dark and broody reincarnation.
