In this edition, how singers went from being just another part of the big jazz bands to stars in their own right.

For many, rock 'n' roll was born in 1956 - the year Elvis Presley made his debut. In fact, its evolution began in America's Deep South more than 50 years earlier.

This edition focuses on the 1960s, a period when British groups - such as the Beatles, the Rolling Stones and the Kinks - took America by storm, threatening a whole generation of professional US songwriters.
