I can vouch for Penge (penje), I was born there, not that it appears on the CoD map. Some oiks liked to humour us by calling it pengee. I have to say it's a place to come from, not go to. If you get my drift. Even after they built over all the bomb sites. Perhaps even
because they built over the bomb sites.
I don't think anyone has a problem with Croydon (croyd'n) but, as we're on the subject, the general couple of miles between Croydon and Penge was locally nicknamed Croynge (croynje) and was also mentioned in the Goon show. I say this only to confuse everbody
I'd also tell you about Llanfairpwllgwyngyllgogerychwyrndrobwllllantysilio gogogoch but the map doesn't extend to Wales.
