Hmm, having visited Dublin a lot lately it has also changed massively. Most service staff are immigrants, largely Eastern European. Property is ridiculously expensive too. I imagine it will gradually become as multicultural as London.
When I lived in Dalston 30 years ago, a visiting friend was confused by the address and numbers. He asked a passerby for help and was told, “Oh yeah, the English people, they live above that shop.”
Our London friends at the time were mainly Irish and Moroccan immigrants, and a couple of Scots and Notherners escaping Thatcher’s grim depressed wastelands. The only London born people I was friends with were Sikh and black or mixed race. The white people from work I was friendly with tended to commute in from Kent or Essex.
Maybe that multiculturalism has now filtered through to the naice bits of London where Mr Cleese hangs out and that’s what is troubling him? But really, it’s been like that a long time.
