I found this interesting, 5 SCOTS (Argyll & Sutherland Highlanders) performing ceremonial duties, but the Pipes & Drums is that of 4 SCOTS (The Highlanders) as you can tell from their Cameron of Erracht kilts.

So... where is the Pipes & Drums of 5 SCOTS? I hope not disbanded due to 5 SCOTS becoming an "incremental Company".
