The link above doesn't work, but if I have the same song, Andy Stewart appears to have written the lyrics, and Jimmy Blue (accordion player) no doubt wrote the music. No other modern recordings listed according to the PRS/MCPS database. My own favourite Aberdeen song (apart from the Northern Lights..), would be 'Bonnie Aberdeen'. which has the adapted tune of 'click go the shears..', not high brow or wordy, but catchy and written by, if I remember rightly, Joe Gordon.
