Ian, I believe that's all she -- er, he -- wrote. I don't think there was another English verse; at least, I've never heard or seen one. Beautiful song...I've loved the melody since my elementary school orchestra played it, in 1963. I was first clarinet. Or maybe second. By the way, there's an interesting exchange of info about the song's origins on this Johnny Mercer FAQ site.

Aloha,
Mark
