Organising rehearsal for dancers

We have decided to email Dave to see whether we would be able to get our A1 dancers out of this commitment to try and use them for a rehearsal because we wanted to get in one more rehearsal before our shoot day (Tuesday the 8th of November) However unfortunately the only day when our whole production gorup are available would be this coming up Friday. The problem is that A1 Students (Cressie and Oriana)  have a compulsory Enigma on that day and therefore in order to ensure that our dancers can be there Evelyn emailed Dave to see if she could get them out of Enigma for that day.

 Here is the email that Evelyn sent Dave:
