A good TV theme tune often can become just as popular as the show itself - and can even eclipse it, in some cases.

Just look at The Greatest American Hero - nobody remembers that show, but you play that music and everyone recognises it. With that in mind, we've come up with ten TV shows and all you've got to do is complete the lyrics for them.

We've tried to keep it varied - from the '80s up to today - and we've even give you a picture of the show itself to help you along. We're practically doing this quiz for you.
