I've picked up a verse for this, goes as follows:

What will you do when the whiskey's gone? Hey ho my Johnny What will you do when the whiskey's gone? Hey ho my Johnny-o What will you do when the whiskey's gone? Sit by the fire and drink hot rum. Johnny is a lad who likes his fun. Johnny is a rovin' blade.

Am I right in thinking there's more? I only heard it once or twice at a Ren-fest, so I may be mistaken on some of the words. I'd love to have the complete song because the tune's in my head and I can't get rid of it. Thanks in advance.
