I first tried to remember this animated series about 20 years ago, and I think of it every few years but get nowhere. Googling never throws up the right programme, and you're about to realise why: I recall almost nothing about it 
Here's what I recall:
CITV
Very early 90s, maybe late 80s but I'm fairly sure it's 90 something.
Theme tune reminded me of Ordinary World by Duran Duran
Animated
Set on an island/group of islands
Opening credits are an aerial view of the island (s)
It is not Charlie Chalk or Cockleshell Bay. It probably wasn't very long-lived.
I'm not holding out much hope, and appreciate that's not much to go on. Please help me to lay this to rest!
