Dear H,
Because!! BECAUSE!! We are Scottish

and a favourite pastime of us Jocks is to poke a sharp stick in the eye of the English, we cannae help it, it's in the blood even if you are a die hard Unionist like myself ( well mostly

) and if you look at the lyrics to the song
And stood against him
Proud edward's army,
And sent him homeward
Tae think again.We are doing just that

I was for a while not a fan of Flower of Scotland until I discovered that it was written by one of my Heroes a Mr Roy Williamson ( who is sadly not with us anymore

RIP Roy ) who was one part of a famous Scottish duo "The Corries" who kind of revitalised Scottish folk back in the seventies, Mr Williamson also wrote Scotland will Flourish but that doesn't have a go at the English, well it does but in a very back handed sort of way

Anyway
"Wha's like us, damn few an' they're a' deid,"Gonnagle.
