My first Beatles purchase was Sgt. Pepper, on audio cassette, when I was in 8th grade. It was totally life-changing-- my parents had brought me up on such lame easy-listening music that I feel like I was hearing something totally new. It might have been almost like what it was like to first hear it in the '60s....
Then I rapidly accumulated the entire Beatles collection on tape and vinyl, and eventually had to switch over to CDs.... But I haven't completed the CD changeover, so some albums I still have to pull out the vinyl for,
