I joined the Columbia Record Club when I was twelve. I had been buying 7" 45 RPM singles, but LP's were now of interest. You got a free LP when you joined the Club (the 1st one's free, kid ;-), and I picked Johnny Horton's Greatest Hits, which included "North To Alaska". I don't have the copy I received at the time, but an exact replacement.
After that it was The Ventures and other Surf bands (big with teenagers at the time), The Beach Boys, and Paul Revere & The Raiders. Everything changed with the English Invasion.
