Me too. Disappointment for us both. Thankfully it faded out about halfway through the '9 German bombers' element.
It's the sort of thing that half makes you want to ask people what they think the point is. At the time it was sung it was clearly part of the 'pro England/anti Wales' repertoire we were going through. Despite my marriage to a Wrexhamian I accept that part of our singing at games v Wrexham - I'm not a snowflake - but that's just bizarre.
