Aaaand a double bill of a stupid song (80s): Agadoo by Black Lace
and it's parody: The Chicken Song from satirical TV classic Spitting Image. See how many puppets of 80s people you can identify in the video! To vaguely tie in with the mystery theme of the site, one of them is Lord Lucan.
Agadoo was judged as 'safe for kids and the sort of thing they'd like' and was often played at parties and school discos. It was widely hated, so when The Chicken Song came out (I was about 9 or 10) we all loved it and after much discussion and arguing nailed the lyrics. Sort of. Then sang it. A lot. On one school trip there was a whole coachload of 10 year olds singing The Chicken Song until the teachers couldn't take any more and made us stop.
I don't remember who figured out what exactly, but I am proud that it was definitely me who got "Eat a Renault 4 with salami in your ears".
For fans of Robert W. Chambers or the Chulhu mythos I think we can clearly see that the video to Agadoo is from a stage performance of The King in Yellow.
Ai Agadoo Fnargn!
