Can I create and post a multi-track version of Sing Gently?

The sheet music and all the learning tools have been created and provided for this project exclusively and the copyright is controlled by Eric’s publishers. Our clearances are for participation in the final Virtual Choir 6 film only. You can post and share your recording of your voice-part as provided for in the terms & conditions, but not a multi-track version (the full piece). Thank you for your understanding.
