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. As a result, the only way to make true stereo mixes of "Love Me Do" or "P.S. I Love You" is through the use of technology that separates out the components of mono mixes. 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 45 rpm mono singles from private collectors have been used as the master for this version of the song. Two other songs in the Beatles' catalogue which also appear in mono on the stereo CDs are "
Only a Northern Song" and "
You Know My Name (Look Up the Number)". Neither of these songs received stereo mixes at the time they were recorded, although other songs that were similarly not mixed into stereo during The Beatles' recording lifetime were not excluded from the set: the stereo mixes of "Strawberry Fields Forever", "Penny Lane" and "
Baby, You're a Rich Man" all made in 1971, the stereo mix of "Yes It Is" that was given a very limited UK release in 1986 on a mail order cassette promotion that Apple and the Beatles did not authorise and was commercially released in 1988 on
Past Masters; and the 2000 edit of "
Day Tripper" from
1. "Only a Northern Song" was first mixed into stereo and
5.1 surround for the
Yellow Submarine Songtrack album in 1999 and a differently-edited stereo mix of "You Know My Name (Look Up the Number)" appeared on
Anthology 2 in 1996. "You Know My Name (Look Up the Number)" is the only track left in the Beatles' catalogue of which the original edit has never received a stereo mix despite the
multi-tracks being available. ==Bonus features==
