Only one wee mistake really, should read 'Let friendship and honour unite'in the third line of the chorus. Note that although it doesn't say so, this second verse, IS actually sung as the chorus

BOTH SIDES THE TWEED
(Words trad, amended by Dick Gaughan / Music : Dick Gaughan )

What's the spring-breathing jasmine and rose?
What's the summer with all its gay train
Or the splendour of autumn to those
Who've bartered their freedom for gain?

    CHORUS:
    Let the love of our land's sacred rights
    To the love of our people succeed
    Let friendship and honour unite
    And flourish on both sides the Tweed.

No sweetness the senses can cheer
Which corruption and bribery bind
No brightness that gloom can e'er clear
For honour's the sum of the mind

Let virtue distinguish the brave
Place riches in lowest degree
Think them poorest who can be a slave
Them richest who dare to be free
