Are those schools? I know he went to Bootle Grammar. I have no idea whereabouts he lived but I'll ask him tonight.
We went to see his old house and meet his schoolfriend once when I was young and his accent came out really strongly - my brother and I thought it was hilarious

Of course everybody there was laughing at how Brummie he sounded though!
@julie56 I used to live in Elm Park and had a friend in Upminster
@wolfie11969 I live on the Erdington/Sutton Coldfield border so the other side of the city. My OH is from Dudley though (Lower Gornal)
