"Love Every Day"
The "ev'rywhere" in the line "You can feel it ev'rywhere" in the middle section is pronounced with an extra syllable. The "-where" is sung to the notes D# and G#, and that interval (a fourth) musically represents that "ev'rywhere.""Leaving Again"
The melody of the first line in each verse has a very strong similarity to the first phrase of the tune "Woodworth," used for the hymn "Just As I Am, without One Plea." In various hymnals I have, "Woodworth" is in D major and Eb major, but since "Leaving Again" is in F major, I transposed the notation:
There are a few differences in rhythm, but all of the pitches are the same. According to my hymnals, "Woodworth" was written by William B. Bradbury, who lived from 1816 to 1868, so - obviously - "Woodworth" is older than "Leaving Again." It doesn't seem likely that this similarity is just a coincidence, but I'm not sure whether it was intentional or not. Aside from this first phrase, the tunes don't resemble each other, so it seems that - consciously or not - Boyce and Hart thought of "Woodworth," used this first phrase (with slightly altered rhythms), but then wrote their own melody for the rest of the song.
"Population"
This wasn't new to me, but since I haven't written about this before, I figured I should include it in this post:Near the end of the song, there are the lines "Well, you may go to college / You may go to school." These lines also appear in "Baby, Let's Play House." I have only Elvis Presley's version, but the lines are exactly the same there: "Well, you may go to college / You may go to school."
"Baby, Let's Play House" is the same song from which the Beatles took the lines "I'd rather see you dead, little girl / Than to be with another man" for "Run for Your Life" on Rubber Soul, so Boyce and Hart's referencing "Baby, Let's Play House" might also be something of a Beatles reference.
