Over his 50+ year career, singer/songwriter Gordon Lightfoot has produced a string of hits. His songs have been recorded by Peter, Paul and Mary, Bob Dylan, even Elvis. He's mostly remembered in this country for his hits from the 1970s and the occasional public TV fundraiser. But Gordon Lightfoot is nothing short of a national treasure in his native Canada. At the tender age of 73 he still spends a lot of time on the road and this Sunday evening his tour bus stops at the Alabama Theatre. Greg Bass talked to Gordon Lightfoot.
