I know it was the game itself, primarily. But all such people tend to identify with a particular team. Can anyone think of a version in which "my brother's" team of choice is specified?

I know the Rolf Harris version on YouTube mentions that he calls out 'Cantona' in his sleep; but that suggests Man United, and as this version is firmly Scottish-based [altho using the Irish tune instead of the 'Fitba'' one], with Hieland bonnets & Scotch names & all such; so it would surely be Rangers or Celtic or Dundee or Partick Thistle or Hearts rather than Man U, wouldn't it; & I think Rolf·H made that bit up to sound contemp when he [clearly] collated his version from various sources: this 'Cantona' refce, moreover, clearly dating WHEN-abouts he did so.

But can anybody think of a reasonably ur-source which suggests which team brother Paul or Jock or whoever might have supported?
