United played Port Vale this day in 1978, there's a picture of the programme for it on Ceres Arabs Facebook.

This story by Sid Loftus is in the comments, thought it was worth sharing here:

"Was at that game. Bus got to ground around 8am then we found a turnstile door open. So bus load of us trooped in to find a dumper truck with the keys still in ignition.

"A few of us jumped in the bucket and got hauled over the pitch in it. Ground staff had a bit of a job on their hands before game."
