A Tyros at Ronnie Scott's? Just for demo purposes, surely? But who knows, these days?

The above suggests James Woodcock simply made an 'audio recording' of the T5's main demonstration.
Can't say for sure, but I'm guessing he didn't actually produce the Tyros 5 keyboard demonstration itself.

I think its many people contributing there playing expertise in different genres to make it all. Then blended together.

I think you nailed it, Donny. These master demos, blown into the ROM of most arrangers, seem to be either an amalgam of many of the factory's best players, or if one guy alone, are not the result of live playing but painstaking sequencer editing of a live take (or several!).
