Well, Lennon did mention matchstick men in his unreleased 1966 song Cheddar Cheese Garden

Let me tell you of a place that's not so very far
Just a block from Kensington place, let's take my Uncle's car
We'll ride the helter-skelter to the bottom of the hedge
Where matchstick men and spastic hens are riding on a sledge

Cheddar Cheese Garden, Hemstead Heath, I want to take you there
Where the air raid warden's nephew, Keith, sits combing his turquoise hair
