Is it Daryl Hannah?
That's all I can come up with, she was in Robbie Williams' video Feel and played a mermaid in the film Splash according to what I have found on Google.
Thanks, patricia. I found something about Daryl Hannah, but didn't make the connection. I shall go with that, in the absence of any other more suitable answer.
Tazmac, I don't think there will be a follow-on quiz for Autism Awareness, at least not for some time. I don't think they are planning on doing them regularly, like we do for the Swimming Pool.
