What was so specail about the televised football match between liverpool and west ham on 15th november 1969?

it wasn't played until the 16th so the camera men and some ground staff borrowed the kits to pretend it took place. 500 kids from the nearby school were moved from pillar to post to make it look like the ground was full. the final score was 15-14 and both sides used 5 subs each. steves mum provided oranges at half-time.
