Ever Decreasing Circles. A puzzlingly unrepeated top-quality classic...

[Darren] Number 25 - Men Behaving Badly?

[rab] re. EDC - funny, we were saying that only last night .. Howard & Hilda - a sublime coupling.

[Chalky] In exactly those words? That's scary. *sweeps the room for bugging devices*

[rab] yup - during Mother's Day Dinner. My sister-in-law has neighbours [married couple] who always leave their house in matching outfits so naturally the conversation turned to ...

[HB] Is it the "advance of the Nazis" moment in Shostakovich's "Lenigrad" symphony, first movement?

Um, "Leningrad"...

[JLE] Right in one. Note to self - try someting more obscure next time.

No 27: Children's TV, definitely 80's, maybe before, maybe after, I dunno.

Dudlo do-didlo-da do-didlo-da
Duh-di-do da-dla-daa
Do-di di-di-didi do-dowo-do
Du-dli-do di-da-dalalala.

I hope this one's easier to guess than it was to type in... I missed out the accompaniment on the grounds of sanity.
