I have been listening to some golden oldies on youtube from the disco era. My friends and used to do the bump till we were bruised (that was way before I had so much padding).
I am gathering the term oldies is determined by age. I nearly had a cow when I hear 80' & 90 are retro! That means that some day they will become the oldies. I always considered 50-60 oldies. Does that mean 50 &60 become classic? But how does that work when 70 rock is called classic. Oh my this is gonna drive me crazy re-classifying things in my head. Just gonna stop. Along as I like my music loud I will be ok!
Hate to say it,but, yep, I was able to do both the bump and the hustle in high school By 1979, I was so tired of disco, I changed to country and never went back
