I know of the song you want; the tune is Whit Jamboree. I can't remember much beyond something like
"On friday nights we take the cars
and we visit a few of the local bars
But there's nothing there which can compare
with the real Newcastle Brown,
Newcastle Brown, Newcastle Brown,
    ...... hanging on behind (obviously not pig-tailed sailors)
Newcastle Brown, Newcastle Brown,
Oh come and get your oats my son.
