I've loved The Kinks' great Come Dancing ever since it came out 30+ years ago but I never knew this about it:
Davies drew on memories of his older sister going on dates to the local dance hall in ‘Come Dancing,’ which ends with her all grown up and worrying about her own teenage daughters. Real life didn’t turn out so well: Davies’ sister died of a heart attack at age 31 while dancing at a ballroom. Earlier that day, she had given her 13-year-old brother his first guitar. This is Davies’ imagined happy ending.Damn.
