There's an enormous amount of work going into alternating vocal melodies and therefore I must give James a lot of credit. It requires him sitting down, figuring out which of the vocal sections are difficult, exhausting or uncomfortable, and finding out the alternative ways of singing them while still staying powerful, convincing and in key. There are quite a few sections and songs to be covered, so I really admire him for the hard work put into all of this. Kudos!
