[4] Ironically Hadden came close to playing football, with trials with both Queens Park Rangers and Forfar Athletic, as well as being offered a contract by Raith Rovers.
[5] In 1983, Hadden was appointed Head of physical education and director of rugby at Merchiston Castle School (MCS) in Edinburgh.
However, when the Scottish Rugby Union was forced to merge the Caledonian Reds with the Glasgow Warriors during budget cut-backs, Hadden returned to teaching at Merchiston.
[10] In 2000 a player revolt led to the removal of Ian Rankin as coach of Edinburgh Rugby.
[11] In April 2005 Matt Williams was sacked as Scotland coach after losing all but three of his 17 matches in charge.
[15] Chris Paterson said of Hadden's influence: "There is a confidence among the guys now and increased skill and belief in our handling... That's a testament to Frank and his coaching team.
"[15] The Calcutta Cup returned to the SRU trophy cabinet on 25 February 2006 for the first time since 2000 after Hadden coached Scotland to victory over England.
[16] The win was largely due to a defensive effort that saw 112 tackles made by Scotland, with only 6 missed.
On 18 December 2007 the SRU announced that Hadden had signed a rolling contract to continue as Scotland coach until November 2008.
