Try ebay and Amazon websites and type in music copies of celebration hymnals.
not sure what our church has done with all our copies as we just got rid of them this winter for the revised anglican hymns new and old or something like that. but getting them to you would be rather a challenge since am in England
if we did have any left.
Good luck, I serve but also sing in the choir and our organist is fab. You'll be okay if there's a choir and keep the choir leader on your side
