the Welsh names didn't seem right

Ach y fi. What a sad story.

Here's a bit of Billy Bragg to take the taste away (you'll probably guess the tune).

"If you ever go to Shoeburyness
Take the A-road, the OK road, it's the best!
Go motoring on the A13.
Well it starts down in Wapping
Then it ain't a-stopping
Bypass Barking and straight through Dagenham
Down to Grays Thurrock
And rather near Basildon
Pitsea, Thundersley,
Hadleigh, Leigh-on-Sea,
Chalkwell, Prittlewell,
Southend's the end!"

Obviously he wrote it as a joke, but (at the risk of Pseud's Corner) I think it works rather well as a celebration of place - it's certainly a celebration of how many placenames you can get into a song. You can hear it, bizarrely enough, on the V&A Web site.
