Lieutenant Colonel Scott wrote back to approve the practice:
In authorizing Piper MacCrimmon to wear your tartan attached to his pipes, a further interesting episode is written in the Regimental History. I thank you for your gracious permission...

Ninth Hereditary Piper to Clan MacLeod. Born Dec 21, 1918. At the outbreak of WWII, a young Malcolm Roderick MacCrimmon of Edmonton signed up with the Calgary Highlanders. His Uncle Art had told young Malcolm of the great pipers who had gone before him. A piper since the age of eight, Malcolm was immediately made a member of the pipe band. George Poulter, a student of the MacCrimmon history and member of the Clan MacCrimmon Society of London lived in Surrey, not far from Camp Aldershot. Malcolm's uncle Arthur McCrimmon arranged for Poulter to meet with young Malcolm. Years of painstaking genealogical research assured Mr. Poulter that the young Canadian soldier was indeed from the blood of Donald Ruadh. In 1942 Malcolm ventured north to Dunvegan Castle...to meet Dame Flora MacLeod of MacLeod and effectively reinstated the line. This was a verbal agreement, which established Malcolm R. MacCrimmon as the 9th Hereditary Piper to the Chief of the Clan MacLeod. As a Calgary Highlander, he studied at the Army School of Piping under Pipe Major Willie Ross. Malcolm was later transferred to the famed Scots Guards and again was entitled to attend the piping school located in Edinburgh Castle. It was a rare thing for a Canadian to be given a transfer to a British Regiment, the story was carried in newspapers all over the UK and Canada. At the end of the war, Malcolm took a bride (Mairi Chisholm) from Gravir on the Isle of Lewis and returned to Canada. They went into farming just north of Edmonton and Malcolm put his pipes away for a few years. Malcolm continues to play at weddings, funerals. City of Edmonton Archives, Robbie Burns Nights gatherings, Remembrance Day Services plus playing for Royal Canadian Mounted Police Mess Dinners for some 48 years plus.
More information can be found at this website, including a history by Sergeant R. B. Worthington which describes among other things the circumstances of MacCrimmon's transfer to the Scots Guards.
The 3 1/2 years in Britain with the Calgary
Highlanders increased Malcolm's contemplation of making a life out of piping, as opposed
to the frustration of just "marching and playing for the Regiment up and down the
length of Britain". He'd also encountered opposition from a senior officer who
objected to the wearing of the MacLeod Clan Ribbons on Malcolm's pipes (even though the
War Office had sanctioned it). These factors resulted in a verbal exchange between Malcolm
and this officer. Malcolm recalls saying ''I want to get out of here, even if it means
going to Churchill to get it. The Officer commented "MacCrimmon, what would make
Churchill so Official?" Malcolm responded ""Well sir, you tell me what
makes him unofficial!"
