Tartan Gannet, actually the HLI didn't wear the kilt - they wore trews. It was one of the reasons why David Niven, on passing out of Sandhurst, listed his preferred regiments as:-
1) Black Watch
2) Argyll & Sutherlands
3) Anything but the HLI
Of course, he went to the HLI, and some humourist saw to it that a copy of his preferences followed him there!
