No doubt The Atholl Highlanders have that right (perhaps in Perth?) , or they would not be doing it. Or, Queen Victoria(?) may have granted them the right to do so for some reason that I am unaware of. Make no mistake, it is a honour for a particular unit to be allowed to do so.
To further Jock's comments, one regiment, the King's Own Scottish Borderers if I remember correctly, was given permission to march with bayonets fixed and colours flying through Edinburgh, on any day "save Sunday". The custom is a throwback to ancient Rome, if I remember correctly, when no Roman Legion was allowed to enter the eternal city for fear of a military coup.
