"Does Your Chewing Gum Lose Its Flavor" and "Rock Island Line" got moderate airplay on the radio in the US in the 1960s. That's how I first heard of Lonnie Donegan.
And the recordings played in the US had it "chewing gum lose its flavor," not spearmint/flavour:https://www.youtube.com/watch?v=Lbg0ZBXnuZE
It came out on the "Dot" label in 1961 as "Does Your Chewing Gum Lose Its Flavor."
The Muppets also performed the song:https://www.youtube.com/watch?v=ZEp8mebBsAI
