@BrokkoliMuskel Everybody that grew up in Britain in the 1970s now has "Wombleing free..." as their earworm!
@rc2014 as someone who didn’t grow up in the 70s, let alone in Britain, can you elaborate?
@BrokkoliMuskel The Wombles was a kids TV show here in the 70s (https://en.wikipedia.org/wiki/The_Wombles). The theme tune starts with "Underground, overground, Wombleing free...". Anything that sounds like Underground overground immediately triggers the Wombles theme tune :-)

Oh, I see, thanks for letting me know.

I’m aware of the Wombles, but I’ve never watched it. I know it from Would I Lie To You.
