An album called Last of The Greys by the Royal Scots Greys regimental band was released in 1971 - from which the track Amazing Grace went, astonishingly, to top of the "Top 40" charts on both sides of the Atlantic.
Up until at least the Second World War, The Greys also had a popular, if somewhat derogatory, nickname of "The Bird Catchers" which derived from both their cap badge and the capture of the Eagle at Waterloo (see below).

At approximately 1:30 pm, the second phase of the Battle of Waterloo opened. Napoleon launched D'Erlon's corps against the allied centre left. After being stopped by Picton's Peninsular War veterans, D'Erlon's troops came under attack from the heavy cavalry led by the Earl of Uxbridge including Major General Sir William Ponsonby's "Union Brigade." The Scots Greys, commanded by Colonel Inglis Hamilton, were one of the three regiments of this brigade. The Greys were said by one eyewitness to have "walked over" a whole French infantry column. The French infantry were caught in a very poor formation for withstanding cavalry and suffered greatly, Uxbridge later claimed that 3,000 French infantry had been made prisoners as a result of the charge.
During the charge Sergeant Ewart, of the Greys, captured the eagle of the French 45th Ligne. The Greys charged the French Grande Batterie and, having cut the traces of the artillery's draught horse teams, came under a counter charge by lancers of Jaquinot's division. Ponsonby, who had chosen to ride one of his less expensive mounts, was ridden down and killed by the lancers. The Scots Greys' casualties, for the whole battle, included: 122 killed; 93 wounded; and the loss of 228 of the 416 horses that started the day.
This engagement also gave the Scots Greys their cap badge, the eagle itself. The eagle is displayed in the Royal Scots Dragoon Guards museum in Edinburgh Castle, alongside the sword wielded by Ewart, who was later promoted to ensign, at the battle.
The charge of the Scots Greys in the painting "Scotland Forever!" by Lady Butler in Leeds City Art Gallery famously depicts the event and inspired the slow-motion shots of the charge in the film Waterloo directed by Sergei Bondarchuk in 1970.
