Permission to use the song

Yesterday I emailed the music company 'Columbia Records' to ask if we have permission to use the song 'I Need Air'. I rang them in the morning but the lady I had to speak to wasn't in the office when I phoned. Her colleague gave me her email address instead.

Dear Shirley,
My name is Rachel Procter and I am an A2 media student currently working on a project where we have to produce a music video which will be assessed by the exam board OCR.
I was given your email address by your colleague who works in your office after getting in contact through the phone this morning.
My group and I would like to use the song ‘I Need Air’ by Magnetic Man for our video and we thought it would be best to contact you for permission to use this regarding copyright issues.
We will be manipulating the video to our own ideas, but the video will only be accessed by the centre and by the exam board OCR. It will be published on a blog as that is the basis of our coursework. The website for the blog is www.blogger.com.
It will also not be used for any commercial purposes, only for us to receive a good mark in our A Levels!

If you would like to contact the centre the address is:
Saffron Walden County High School
Audley End Road
Saffron Walden
Essex
CB11 4UH

Telephone: 01799 513030 and ask to contact Mr Canning or Mr Hansard in the Media Dept.

I hope that you will allow us to use this brilliant song as we feel that we could use it to the best of our ability to produce a piece for us to get great marks at the end. We will send you a copy of our video when it is completed to prove that it is only being used for exam purposes.

Thank you very much for your time, I hope to hear from you soon.

Yours sincerely,
Rachel Procter
