Your First Vinyl Album.

First single 78, Let Me Go Lover by Joan Weber
First single 45, Down The Road by the Cadilacs

Mountain "Climbing" I was 12 yrs old

Either Johnny Winter, "Second Winter", or Savoy Brown, "A Step Further", cannot recall which was first, though they were the first two. $3.99 at the Woolworth IIRC. Of course, that's if you paid retail. My friend's sister worked the cash register and HEAVILY discounted all album purchases for me. (Bar code scanning was yet to be used.)

Goodbye Cream and Sgt. Pepper, 2 albums for 5 bucks in 1969. I bought them with my own money when I was 12 years old.

Chhech and Chong "Big Bamboo" Laughed so hard I cried for the first half dozen times I listened to it.
