Hello, I have a question about the work of John Williams about "Por una Cabeza".
My friend Tomoko - professional pianist and composer, was inspired by the YouTube video of "Por una cabeza " performed by John Williams & Itzhak Perlman and she arranged it with her originality.
As a professional musician, she would like to perform her arrangement at her concerts and on YouTube, also she would like to sell her arrangement on online platforms.
She already contacted Hal Leonard and Alfred Music which published the musical sheet of "Por una cabeza". She would also like to have permission from Mr.John Williams due to his right of "musical arrangement".

Is here a proper place to discuss? If no, can anybody suggest where to contact?
Thank you very much.
