No stereo mixes exist for the 1963 single "She Loves You" and its flipside "I'll Get You" or the 1962 single "Love Me Do" and its flipside "P.S. I Love You". It was the practice at Abbey Road Studios prior to early 1963 to wipe and reuse master tapes once they had been mixed down to mono for single release.Please Please Me booklet, p. 18 For this reason there will never be true stereo mixes of "Love Me Do" or "P.S. I Love You". Although the practice had stopped by the time of the release of the "She Loves You" single, and although it is possible that the master tapes were in EMI's possession in January 1964, when the German language version was recorded, it is commonly believed that those tapes were either stolen or destroyed. Competent-sounding stereo versions of "She Loves You" have been created unofficially using the backing track from "Sie Liebt Dich", but the engineers who prepared the remasters elected not to do this. Every release of these four songs has been in mono (or simulated stereo) and they appear in mono on the stereo version of Past Masters and Please Please Me. This is also the case for the single version of "Love Me Do" with Ringo Starr on drums but at some point, even the mixed down mono tape of this version of the song was lost. Some authors have expressed the opinion that the original version of "Love Me Do" was intentionally destroyed in order to alleviate possible confusion between it and the more common version of the song. Since 1980, new transfers sourced from reasonably clean 45rpm mono singles from private collectors have been used as the master for this version of the song.The Beatles In Mono box set booklet
