Overdubs included a double-tracked lead vocal by Paul and backing vocals by John and George. A good deal of time was then spent on George trying to do a flourish using the tremolo arm of his guitar for the end of the song. The seventh attempt (out of ten) was deemed best. The following day, however, Paul elected to do it himself, even adding a lead guitar passage throughout the song, thus usurping George's role for the second time in two days.
The song itself is a rather lightweight piece, with lyrics that are truly callous in the manner that the singer dismisses one girl in favor of another. Though McCartney also offered Tell Me What You See for the soundtrack, Another Girl was probably chosen instead due to it being a more uptempo number.
On February 27th, less than two weeks after recording the song, the boys were in the Bahamas miming to it. It is the final new number to be introduced, appearing quite late in the film. The sequence shows the band playing on a reef and cavorting with some girls in the water, with Paul occasionally using a girl in a bikini as a stand-in for his bass guitar. This was the last time the Beatles would ever perform the song in any way.
