A few weeks ago I had a chance to see The Crooked Stovepipe band from St.Johns do the original tune by Ron Hines ??(Hynes) After they were through, they stopped and told the following story:

Apparently, some years ago, when "Sonny's Dream" first became popular, there was a pub in Charlottetown, P.E,I, that played host to a lot of touring folk bands, ensembles and singers. It seemed like everyone was singing "Sonny's Dream" during every set. It seems that the pub kept their back door open and a lady who lived across the alley was subjected to a summer-long serenade of various versions of "Sonny's Dream". She wrote a tongue-in-cheek parody version she called "Sonny's Dream: 25 Years Later" where Sonny has grown old and fat and is now a burden on his mother who is trying to encourage him to finally leave the nest.They followed with the parody version.

I don't know the author's name or the whole song but the chorus goes:

Sonny, please go away! Leave me here all alone!
Your Daddy's the smart one; he never comes home.
If you eat any more, you'll go right through the floor,
And I'm starting to wonder, if you'll fit through the door...
oor...orr!
