It was the summer of rock'n'roll. Bill Haley. Buddy Holly. Chuck Berry. Fats Domino. The Big Bopper. Now, every time I hear one of their songs, I am reminded of a summer vacation never to be forgotten ... for all the wrong reasons! Certainly, much of it had been spent lazing on a lounger beside a swimming pool, immersed in an interesting book I had brought along. However, my ears had been battered for days by continuous rock'n'roll, blasted at maximum volume from a tinny cassette machine leant against the wall of a Spanish villa's veranda. This was not the preferred soundtrack of my teenage years.
