I was 15, and my boyfriend brought me a reel of quarter inch tape that had all the “Underground” music of the 60’s, which later evolved into the Rock of the 70’s.
I played that tape on my dad’s “Roberts” Reel-to-reel Tape recorder so many times it got all stretched out.
And yes, VU was well represented.
