"\"Highland Laddie\", also known as \"Hielan' Laddie\", is the name of a Scottish popular folk tune \"If thou'lt play me fair play\", but as with many old melodies various sets of words can be sung to it, of which Robert Burns's poem \"Highland Laddie\" is probably the best known.Highland Regiments raised in the 18th and early 19th centuries employed many unique symbols to differentiate themselves from other regiments and enlisted distinctive music to announce their arrival, but as a result of the Cardwell Reforms of 1881, all British Army Highland Regiments were required to use \"Highland Laddie\" as their regimental march.
