Hedgehoppers Anonymous

Does anybody else remember one hit wonder Hedgehoppers Anonymous with their 1965 song It's Good News Week. They were actually all RAF workers and very nearly didn't get off the ground (sorry for pun) as they hadn't got permission to be involved in other employment. Considering the first verse of their song they were lucky to get permission.... 
"It's good news week. 
Someone's dropped a bomb somewhere 
contaminating atmosphere 
and blackening the sky". 

In extras - Man power swans.
