Shortly after writing about "A Hard Day's Night" at the end of May, I thought I realized something else about the song just in playing it over in my head. When I listened to the second disc of Live at the BBC a couple days ago, I was reminded of this and was finally able to confirm it.
In the lines "I find the things that you do / Will make me feel alright" and the first "You know I feel alright" at the end, the "al-" of "alright" is sung with a melisma (Bb C), musically giving something of a sense of the completeness of the feeling.
