In looking through old clippings, I found some Record Collector mag stuff from 1983. Record Collector's Nick Piercey is interviewing Mike Heatley of EMI: RC: Did the Beatles re-record those songs for Germany or just sing to the pre-recorded backing tracks? EMI: "She Loves You" had to be totally done again, as all we had originally was a two-track tape, and it was the practice in those days to scrap the two-track tape as soon as the mono master had been made, because you had no further use for it. So as they didn't have the 2-track tape, they had to re-record the backing also. "I Want to Hold Your Hand" was recorded originally on four-track, which meant they could use the rhythm section of the four-track and put on a new vocal--and I think some added guitars as well. In fact, checking my files, a four-track copy of the tape was made from the master for the Paris recording on 21st January 1964. No such copy of "She Loves You" was made. So that proves it.
