 In the 1960s, there were a group of studio musicians in Los Angeles that became known as the Wrecking Crew. Now, I call them the melting pot of America's pop music. Italians, Jews, Irish, black, classically trained jazz musicians, country musicians, hillbilly, and one woman. Now, together for a few years in the mid-1960s, they ruled the Billboard charts with their recordings. They were a hidden secret among music buyers and listeners.
