Hold on - if Stouthearted Men came from the same Gilbert and Sullivan light opera as Is Life A Boon?, then it came from The Yeomen of the Guard, NOT Brigadoon, so I volunteered some erroneous information. Yes, it was definitely NOT Brigadoon. It DEFINITELY was The Yeomen of the Guard.

My memory is not what it used to be (and may never actually have been as good as I used to think it was...)

Metchosin, thanks SO MUCH for sharing the Shooby scat version!
