All I've found, from, of all places, an anonymous comment to a geology forum in 2017:

"I came across a child of Cork
He was vomiting in the road
He was throwing up his load
And this he told me

I'm going down to Kilburn Park
Going to join McAlpines' band
Going to desecrate some land....
etc etc.
is wonderful and equally dated.
