Bradman is immortalised in three popular songs from different eras, "Our Don Bradman" (1930s, by Jack O'Hagan), "Bradman" (1980s, by Paul Kelly), and "Sir Don", (a tribute by John Williamson performed at Bradman's memorial service). Bradman recorded several songs accompanying himself and others on piano in the early 1930s, including "Every Day Is A Rainbow Day For Me", with Jack Lumsdaine. In 2000, the Australian Government made it illegal for the names of corporations to suggest a link to "Sir Donald Bradman", if such a link does not in fact exist. Other entities with similar protection are the Australian and foreign governments, Saint Mary MacKillop, the Royal Family and the Returned and Services League of Australia.
