After its 2013 at Detroit's Campus Martius Park was washed away by heavy rainstorms, the Average White Band is happy to get a chance to make good on the date - partly because it hates to miss a show, partly because the members just love the city."We love the Detroit audience," says singer-bassist Alan Gorrie, one of two founding members - along with Onnie McIntyre - left in the Scottish R&B group, which is celebrating the 40th anniversary of its signature hit "Pick Up the Pieces" this year.
