I regard Flower of Scotland as my National Anthem.
It is the song which is sung by our national sporting teams at the start of major events.
I would be outraged at the prospect of ditching it.
God Save the Queen, well I consider it to be the English National Anthem. It is however also the Anthem associated with the united defence forces which defend the British Isles, namely the British Army, The Royal Navy and The Royal Air Force and the first verse is proudly sung here in Scotland at the end of our church service on Remembrance Sunday and at military and Royal events. I would never dream of singing the other verses, even if I knew the words, and one of the verses is known to be distinctly anti-Scottish.
