It was 1971, Ortonville, MN in a Ben Franklin dime store. (anyone remember those), The album was The Best of the Jackson Five. I'd seen them on American Bandstand.

The first album that made my parents cringe and shook the vase and candy jar off the Montgomery Wards stereo console was Led Zep "Physical Graffiti". That one still sounds good today.
