Born in Krugersdorp Andy van der Watt went to Maritzburg College in the days of the great Skonk Nicholson, played for Natal Schools at the first Craven Week, and then, after the Air Force Gymnasium, to Stellenbosch University in the days of the great Danie Craven. Small wonder that when he was a schoolmaster at Hilton he coached the rugby with great zest. He was the Hilton coach when Gary Teichmann, Bob Skinstad and Wayne Fyvie were at the famous school.
Van der Watt played provincial rugby for Western Province, Border and Natal. He became a Springboks on the 1969-70 tour playing in 17 of the 24 matches, including the Tests against England and Ireland.
