Not only fingerprints on the music but absolutely big sticky fingers in the clergy that led prayers during the service. A lot of people definitely noticed Bishop Curry's reference to love sustaining people during the times of Antebellum South but as far as I know, no one has picked up on Reverend Rose Hudson-Wilkin who led one of the prayers for Harry and Meghan. A simple Google search will tell you much more about this wonderful and passionate woman.
The selection of the Coptic Orthodox Archbishop of London, Archbishop Anba Angaelos definitely points to Charles. This is man that is eclectic when it comes to matters of faith, IMO, and just may signal some changes he'll make when his time comes. That's a subject for another thread though.
