On that subject, how do you go about sustaining your voice for what is a marathon of a singing part as Jesus.

I am incredibly focused on looking after my voice. There was a guy I met years and years ago called Philip Griffiths, who is the longest serving person in a show in theatre history in The Phantom of the Opera. He is a singer, a tenor. I did Chess with him in London.

His advice was wake up in the morning and don't do anything for two hours. Drink tea, drink water and warm your body up naturally. Just potter about. Then after hydrating yourself, hum for about twenty or thirty minutes.

Because your vocal chords are the least useful thing in your body, all they can do is make a sound, so they are the first thing your body dehydrates if you have dehydration and they last thing that they hydrate. So when you are completely hydrated, you have to warm up for two hours. Basic scales, octave leaps, humming. Then shut up for the rest of the day. 

Do a personal warm up before the show, then your show warm up. Keep your voice warm until your start your performance. That is a full days work to prepare vocally for an evening show. I do that every time that I sing. By the time I open my mouth on stage I have been warming up for about four or five hours. My voice is stronger and younger sounding now than when I started out.
