Rocio Guitard who was the choir director is also a singer. She joined the project and added her voice to the song by featuring as a soloist. Originally from Spain, she lived some time in Germany. Because of this, she can speak and sing in numerous languages. She resides in the bay area.

Sandy Cressman was the singer who sang in Portuguese on the album. Very talented herself, she also contributed greatly to this project.

It was amazing to hear the incredible talents of the more than 60 vocalists but what was more amazing was to see how everyone encouraged each other. Even though there were so many differences in singing styles, nationalities and backgrounds, everyone had a great time together. It was truly a pleasure. We couldn't start expressing the amount of gratitude we have for each and every single artist who put his hand to this project. "If You Believe" was supposed to be about people. In retrospect we can truly say that it was about people, working together, helping each other and enjoying all that life has to offer. Thanks to all.
