Hello I'm afraid that Georges DELERUE has gone to the grave with his beautiful compositions. According to the SACEM he was himself the publisher and the USA is very far. Difficult to find heirs, if however they would have kept something. The quickest solution, not necessarily the cheapest, is to find a generous copyist who will make you a very nice musical record. If you want addresses I can communicate them to you, it is not less than 100 euros the title, but it is neat work. After the price can be reduced according to what you want. The melody alone can make 20 euros. Have a nice day in music.
