I'm 48 as of 2017. My aunt lived Sagemont in the 1970's and I'd sometimes stay out there. I grew up in Wilchester neighborhood off Wilcrest between Memorial Drive and I-10. Anyway, I would skate either at Dairy Ashford Roller Rink over on my side of town or Almeda Roller Rink, which I believe is now closed. And yes, I only remember them playing lots and lots of disco on the PA system. Hope that helps!
