It was a "bubble trip"...
ie away tickets only sold to supporters who were registered on the club's database,
they had to travel on official supporters coaches,
the tickets were then collected via the police from a motorway services station on the outskirts of Leeds,
the coaches were then (police) escorted to the ground (which incidently they got to 15 mins AFTER kick-off)
and after the game (With City fans held in the stadium for 30mins) the coaches were (police) escorted out
of Leeds & not allowed to stop.
Hence, no "dancing" before or after the game.
Not the first away trip like this, nor likely to be the last
