Saw lyric notes about the song about the Swanage Railway.This I believe was by the Yetties folk group.
However there was an earlier song about the Swanage Railway which I wrote (is it ethical for me to say this here?):
It was recorded (45prm single) by band: Cottage Industryin the 1980's ( on Rural Records based nr West Moors, Dorset) and the idea was to raise funds and create publicity for the railway preservation campaign - which it did qiute well.
