I listened to Caught Live + 5 yester-day and noticed two melisma'd "go"s in "Please Think about It." "Go" in the backing vocals after "Don't go" is sung to the notes E D C, and "Go" in the lead vocals in the line "So, if you have to go" is sung to the notes G D E D. For both, the articulation gives a musical sense of movement.
To-day, I also finally lookt into something I noticed years ago: that the beginning of "Please Think about It" is somewhat similar to the beginning of "I Don't Mind" (actually, the particular elements are repeated throughout both songs, but it's easier to identify them simply as "the beginning"). I don't think the rhythms are exactly the same, but they are very similar. Although the two songs are in different keys, the root notes of the chords at the beginning of "I Don't Mind" (D F G) have the same intervals as the bass notes at the beginning of "Please Think about It" (B D E).
