 Waller's relationship with Stewart and Wood served him well, as he would go on to join them on the next three Stewart solo albums, "Gasoline Alley", "Every Picture Tells a Story" and "Never A Dull Moment" The coupling meant that Waller played percussion on Stewart's transatlantic chart topping hit single, "Maggie May".Waller also shared drum duties on Stewart's "Smiler" album - the opening song of which contained Waller's dog making noises.In 1971, Waller joined the Long John Baldry blues band for Baldry's first tour of the United States.
