Name a tune that.............

Looking through this thread again (I was actually searching Fremder99's posts to find a track to RQ for his birthday ) I realised that this might be another thread to ressurect for some of the newer moonbuds and budettes. It's a good way to try and delve into your psyche and see what makes you tick. The more we understand about people the less chance there is for conflict.

So get thinking.

The question was:

Can you name ONE track that totally sums up the "Prog" ideal?

I'll set the ball rolling by saying "Cinema Show". I reckon that it has it all. Great music, changes in time, great lyrics, great instrumental sections and it's longer than 4 minutes duration.

Any others?
