Yester-day I listened to Friends, 20/20, and Sunflower, and I found a number of mostly small points to write about.
In "Friends," the first line is "We've been friends now for so many years." The "many" is sung with a melisma (F# E F# E), musically giving a sense of number. When this line is repeated later, however, I don't think it has this feature.
