"Good times and bad we were there for each other. He was like the air that I breathe, always there, always close by." This double-delivery of Martin magicdocuments all you need to know about his ability to communicate and to personalise some of the greatest songs ever to be plucked from the pages of that well-thumbed Great American Songbook.
