Gareth Mitchelson Championships are held at the Cowal Gathering in Dunoon on the last Saturday in August each year. Whilst still at school Mitchelson was a member of the world-renowned British Caledonian Airways pipes and dance corps, performing at Scottish events all over the world. In 1985 Gareth and Deryck Mitchelson commissioned new work and music for inclusion in Glasgow's Mayfest dance festival and formalised this with the formation of the CelticSpirit Dance Company as a limited liability company. Other notable performances have included participation in many folk festivals and fiddlers' rallys, in the Capitol Theatre and His Majesty's Theatre in Aberdeen,
Highland Scottish Orkney Coaches Ltd) by Stagecoach Group had been finalised. Highland Scottish can be traced back to 1952 when Highland Omnibuses was created when Highland Transport, Macrae & Dick and Alexanders Town Services in Inverness were joined together. In the reorganisation of the Scottish Bus Group, in 1985, to prepare for deregulation and privatisation, the company was renamed Highland Scottish Omnibuses Ltd. Unlike many of the original SBG subsidiaries, Highland's operating area remained largely unchanged. No additional territory was gained, but Oban was transferred to Midland Scottish. The red and grey livery used by Highland Omnibuses was retained for the fleet.
