A formative audio experience for me as a freshman in high school was figuring out that I could patch the little stereo in my room so as to remix those early stereo LP releases to mono and use the balance control to crossfade between channels. I carefully planned and noted times for the x-fades to make interesting cassette dubs of versions with all instrumental sections, sparse vocal versions sections missing key instrumental tracks, and other oddities. It was great fun, a learning experinece, and the resulting cassettes impressed my parents and amused my friends at least.
My appologies to the original artistic intent of J,P,G,R, & GM, but the entire novelty and interest in doing so was entirely based off the fact that all of those Beatle songs are so completely and unalterably seared into everyones memory in their original form, and the concept of sampling and remixing was still a few years off and had not entered the public consiousness at large.
