I'm getting behind in writing about things I'm noticing as I continue to make my way through The Complete Albums Collection box set for a second time. I listened to Ammonia Avenue on 29 November and noticed a small thing in "Dancing on a High Wire." In the line "You need to be so sure" at ~3:55, the "sure" is sung with a melisma (G F D), musically giving a sense of degree (for that "so").
In referencing the recording again now, I noticed that some of the "so"s in that recurring line are also sung with a melisma (C D), also for a sense of degree.
