I couldn't tell you which decade or name a song they sing. I wouldn't recognise their music if they played it at my funeral. I must have missed them somewhere along the lines. And that suggests to me that they were big in the 80s. The 80s was when I had babies who became toddlers who became children.
I missed most of the 80s.
Before that programme, File on Four was looking at the problem of child abuse in madrassas, after-school schools for Muslim children to learn and memorise the Koran. Amazingly the strict rules about corporal punishment and child protection that apply in state schools don't count in religious schools, and teachers who have been found guilty of abuse are still able to teach in madrassas.
It's amazing what I learn when I'm making stew.
