Hello everyone, I know that the topic has already been covered here but I need a confirmation from you because I can't find anything on the web to be sure I'm not doing anything wrong.

i'm working on a movie soundtrack and i'll have to do a new arrangement of "the parting glass" for the final scene and i need to figure out if i should ask permission to use it.

I repeat, the new arrangement will be original and re-performed, obviously the words are those of the traditional song.

I add that I would like to deposit the entire soundtrack with a copyright management company.

I hope I was clear and that someone can help me understand how to deal with the music and lyrics of a traditional song within a movie.

Thank you

Luciano
