Get Funky In Cardington Hangers is a classic dub version of the A-side tune: it drops the main synth riff and vocal sample and focuses on bass, breaks and an improved acid line. Besides crowd noise, it also adds new synth elements, but these are *very* low in the mix, I personally didn't even notice them at first.
Get Funky! on the A-side is still one of my breakbeat hardcore faves; even though or probably because it's just the simplest of ideas arranged to maximum effect.

You get two versions of the same tune for your money - the B-side is my preferred choice as the A-side overdoes the Fast Eddie sample, while the flip opts for a sparser sound relying on a simple, catchy synth and breakbeat combination to deliver the goods.
