Asking permission to film

As we are using actors in our music video which do not come to this school, we have to get permission to make sure that they are allowed on to our school premises.
Here is evidence that we emailed our media teacher to ask her if this would be okay and if she would be there for health & safety reasons.

Here is the email which i sent.

Here my teacher replied "ThaTs fine lauren, I will be here. J" This shows that we have been given the okay to get outside students into our school to be able to use them to film.
