Is this a folk song? I've never heard Lonnie Donegan's version, but I recall Ramblin' Jack, Pete Seeger, and maybe Woodie Guthrie do it on record and many others do it live. I'm pretty sure Lonnie Donegan didn't write it (I know I heard this tune before I heard Does Your Chewing Gum Lose It's Flavor On The Bed Post Overnight). Do we know who did write it or is it P.D.?
