I had the pleasure of watching Dag often at Tilehurst when the sport was big in Reading, and later he was an outstanding number one for the Rebels at Oxford.
Superb stylist and so effortless, his prowess in the wet came from practicing on ice in Norway on a conventional speedway bike it was said. He was the last man to ride a JAP in a world final but in the end they couldn't get it to work with the silencer.
His elder brother Ulf was a good rider and a tough guy, a Norwegian army sergeant.
