Equally poignant is the medley of the Last Post with Waltzing Matilda. I first heard it played at the funeral of a mate (a former bandsman.) I then tracked it down to a compilation CD of Macca's, by I think the 3MD band (they did just the one song amongst a heap of other artists.)
There is a You Tube version
