I'm trying to find a sketch where (I think) Newman and Baddiel's "History Today" characters did a draw for the FA Cup final.

I'm pretty sure I've seen it online before, but I can't find it now.

Does anyone know where I can find it, or at least confirm my memory of the sketch?

This definitely happened. Pretty sure it was 1990 - because I remember it as:

no.1 Crystal Palace will play.... no.2 Manchester United
and that concludes the draw for the FA Cup Final
