I've consulted Ms Google Mike It depends which version of my rebus you want. You can have George Formby or Herman's Hermits amongst others. One's 1937 & the other's 1966. (oh dear it's that year again ) As far as I can see Jack's rebus was a hit in 1959.
I'm very happy to stand corrected
It's turned out nice again
George Formby's 'Lamppost' was 1937
Lonnie Donegan's 'bedpost' was 1959
However, as Jack mentions in his spoiler, the 'chewing gum' song itself (but with 'spearmint' in the title) goes back to 1924!
Never mind! Let's not get pedantic!
My offering today is something that John Donne, the preacher and poet wrote in 1624, 300 years before the 'spearmint' song;
