Evidence of email regarding song

We have contacted the band's manager for the song we intend to use for our project. We are now awaiting a response from him to say that it is acceptable. If we do not receive a response, we will assume it is acceptable for the song to be used. I have taken a printscreen to be used as evidence.

The email reads:

Hello, I understand from Madina Lake's Facebook page that you are their manager. I was inquiring to see if we could use segments of their song "Hey Superstar" in a fictional film opening for our A Level Media project for our school (Ken Stimpson Community School.)

Many thanks,
Dominic Waldron
