help me find this british song or band!
 

I cannot remember the title of the song which I've heard few years ago.
It was made by a group of elderly ladies, particularly British. Their genre was absolutely comedy and very hilarious. I only remember one of their famous song, was about the difficulties and awkward moments which elder may face once trying the new sex position, i.e., doggy, in the car.
Any Idea?

Sounds like "Dogging" by Fascinating Aïda.
