I recently listened to the 2 CD Anniversary Edition of Sgt. Pepper again and noticed a small thing about "Lovely Rita." The two notes of "away" in the line "When it gets dark, I tow your heart away" are sung with a fairly wide interval (a fourth: C to F). Musically, this gives a sense of the movement in "tow[ing]... away."
In comparing the take on the second disc and the final version on the album, I discovered that the final version is a half-step lower. I referenced the liner notes, which confirm this: the tape machine was run slower, dropping everything in pitch.
