Wasn't there another song with a chorus line of

"Johny, lovely Johnie, Would you leave me..." ?

Dredged up from long long ago, I think it was one of those roistering ones about a soldier leaving his girl to go to High Germany or one of those other places that always appeared in folk songs, but not on maps. It must be thirty years since I heard it and that's the only line that has stuck. Now that it's come back, can anybody help with the rest?
