Sunday Summer's Ending Earworm

Whence this? Big shit on the radio in (early, pre-Beatles) nineteen-sixty-fucking-three; how often since have I heard it that it wormed its way inside my brain?

Once possessed this disc, so I was thinking King Yellow rather than Cliff Richard.The humanoid mind is an amazing thing, especially at an advanced age.
