First of all ~ I agree 100% about Rev Jack Day! He was wonderful!!!
Second ~ I am Russian Orthodox and my DH is Jewish. Needless to say, there really isn't any ceremony out there already to perform for us. So I spoke to Rev Jack on my site visit, and he told me he will do whatever it is we wanted. We had a loving ceremony, with a few traditions from each of our backgrounds. We made up the entire ceremony ourselves, and Rev Jack performed it as if he had written it himself.
Good luck!
