Born in 71. My bro is 6 years older. We shared a room. He was a casual Beatles fan. Had the blue and red albums and that's it. I always listened to the blue album. When I was about 10, I bought Wings Greatest Hits. Remember it like it was yesterday. Was out with my mom. Bought the album on vinyl. Then we went to visit my grandmother, where I played the album on her console stereo. That's when I got hooked on Paul.
Similar story ... out with Mom .. bought Billy Joel's Songs in the Attic on vinyl and brought that to my grandmothers to play. Totally off topic, but that album is phenomenal.
Back on topic ... I didn't start diving deep into the Beatles until I was well into my 20s .. maybe even early 30s. Prior to that, I was a very casual fan who loved what I'd heard, but was never inclined to buy albums and really listen.
Better late than never, I suppose!
