I recently listened to some live versions of "This Old Heart of Mine" and noticed two small things.
"Away" in the line "Each time you break away" is sung with a melisma (B B A), musically giving a sense of movement. (Note that this is only in the version recorded on 1 November 1966 for Saturday Club [track 26 on disc 4 of Zombie Heaven, track 13 on disc 2 of The BBC Radio Sessions]).
The second "more" in the line "Hurting me more and more" is also sung with a melisma (E F#), musically giving a sense of the growing amount.
