I worked on The Bacchae for the National Theatre of Scotland and Piaf at the Donmar, both of which had lots of - obviously with Piaf, but The Bacchae as well - lots of singing in it. So really I' d say they were far closer to a musical than many plays. I think usually with a play it' s a lot more instrumental cues, a bit less singing. With Piaf we had 20 numbers in it, and similarly with The Bacchae. So there' s varying degrees of singing within it. That is why I was brought in, that' s what I do, more vocal work, whereas on a play you' d often have more instrumental cues.
