Query: Fun and informative read!

For Bill Haley fans this is a must read, and even the casual music history buff will enjoy it. The book contains interesting and relevant details, but not so much to wander away from the main topic or resort to "filler." If you don't know the story and characters behind "Rock Around the Clock," this is the perfect book to hear the rest of the story. Lots of pictures, too! Highly recommend.
