I don't have anything to say about "And We Were Young Again" (so far, at least), so I'm skipping ahead to "Maybe Tomorrow."
In a number of interviews, Rod Argent's explained how they had to get Paul McCartney's permission to quote a line from the Beatles' "Yesterday" at the end ("Just like The Beatles used to say / 'I believe in yesterday....'"), but an-other line in the song is "Baby, we can work it out," which might also be a nod in the Beatles' direction (specifically their song "We Can Work It Out," which is also about trying to resolve an argument).
The more interesting thing I noticed about the song, though, is the line "Kick out the quarrel, baby." There's alliteration between "kick" and "quarrel" despite the words' starting with different letters, and, in some ways, the whole conceit of the song is contained within this one element. There are two people at odds with each other (in the same way that "kick" and "quarrel" start with different letters), but despite that, they still have a close relationship (in the same way that "kick" and "quarrel" are alliterative). As the song itself describes it, "We still got the love inside / You know there's nothing to doubt!"
