Wikipedia handily translates into English and Gaelic.
Most Scots, and I'm sure a fair good few non-Scots, know about this auld sang, but for those that don't: "Robert Bruce's March to Bannockburn," known more commonly as "Scots Wha Hae," was written by Scotland's most celebrated poet Robert Burns in 1793. Though the speech itself is conjectural, it was written to the tune of "Hey Tuttie Tati," a traditional Scottish tune of ancient lineage, which was widely believed to have been played by the Scottish troops at Bannockburn.
