Thanks, Willa, much appreciated. Cockney slang appears more and more in the States and Canada. I always thought kicked the bucket was American (Mencken, "The American Language," says it is, and western). But it could well have been brought over by English immigrants who went west. A "Swell" was common many years ago, but has pretty well vanished. "Derby kell" is new to me. We used to call a big stomach a "corporation." I think "dial" is everywhere; it is claimed by the Scots as well.
