Andrew Chalfoun shared his competition tune “Struan
Robertson.” Andrew is an 11 year old piper from
Maryland. He plays with the Guilford & Glencoe Juvenile
Pipe Band. Fionn reminds us of the tradition in the Clan
Donnachaidh that this tune was composed to commemorate
the appearance of the Clan at the Battle of Bannockburn
and that indeed the tune was also known as Teachd chlann
Donnachaidh – The Coming of Clan Donnachie. Their
arrival did in fact have a great influence on the course of
the battle and Robert Bruce expressed his gratitude by
desiring that the chief named his oldest son Robert.
Following a further service to Royalty some generations
later, the name Robertson was adopted by the clan.
