Been working on this a bit - I think it could be William Orbit.
Check out the these Bass-O-Matic videos - chuck them side-by-side to the Energy 89 keyboard player.

A lot of his tunes tend to have really good intros, which this energy 89 tune certainly has.
He'd for sure be floating around the scene at the time and have the talent to perform.
I've almost convinced myself it's him - what you reckon?
