Well, they played this again yesterday evening (10th June 2022) on the 'Now 80s' TV channel with the accompanying video, and I unwisely didn't turn off the sound. I cried and cried, it just seemed to break my heart all over again. Another time, I must change the channel until the song is over.
I've never known any song to have this poignant effect on me, apart from 'Will Ye Go Lassie Go?', which a chap played and sang in the Edinburgh folk club when I was a 17yr old student. (I was rather timid, lonely and lost during my first months in Scotland.)
Doesn't music have enormous power to affect ones mood and emotions?
