Jaws - Even The Music Is Scary

Today i watched a film i watched years ago. It called JAWS and its about a dentist, no its not really, its about a shark, a great white shark. Great white sharks are called that because they are great and white and er... sharks. My sons Lilly and Rose, sorry, Ben and Jack watched it and Ben said that even the music at the beginning is scary. He's right. It is. The music goes like this....Bumbum, bum bum, bumbumbumbumbumBUMBUM. That's a lot of bums. Jaws is a great film though. And its not even about bums. Whats that all about????????
