Better give you some answers then...

First of all, the quiz...

People obviously found this hard. 
One second was long enough to give people a good idea of what they were hearing, without it being long enough to nail it. I think 2 second clips would have been a doddle. Half second clips would be almost impossible. One second tantalized and teased in a way that no other time could.

Congratulations to Peter, who out of the billions of people on this planet, was unique in correctly identifying any of these.

Some of these are a bit obscure. Some are not well chosen samples, but some I think you'll wonder how you didn't recognise them.

Hope you enjoyed it anyway.
