"I'll Be Back"

Last night I figured out some of the brass parts for the Buckinghams' cover of "I'll Be Back."  This morning I was still thinking about the song, and I realized something that also applies to the Beatles' original.  "Surprise" in the line "But I got a big surprise" is sung with a melisma (D C# B), and that extra note helps musically represent the "big[ness]" of that surprise.
