Hi Andy, welcome to a kindred spirit! You know, I’d never really noticed or thought about Mendhurst – I haven’t a clue what that might be. Lyndhurst, maybe, or Medhurst, or Mendhirst? I think that’s the rapid-fire part of the song, isn’t it, so it’s hard to make out.
As for the wee places, I love the juxtaposition of ordinary English places with the exotic and famous places abroad. In keeping with the song’s English accent and the English origin of the band, I’d be tempted to go with any English place by default.
Of course, this is entirely academic, but as you say it’s fun to think about it.
