Toto Hosanna?

I expressed the desire a while back to work on coming up with some progressive Christian music for use in church services – whether congregational singing or solo performance. Although I’ve kept coming back to this idea, and wishing I had more time to focus on it, the fact that someone else with a similar interest recently contacted me, asked if I had come up with anything, and shared some of his and his wife’s music, got me thinking more actively about this. Hopefully I’ll find more time to think about and work on this soon.
In the mean time, I don’t worry too much about the lyrics, and am mostly content if from time to time a song provides an opportunity for a keyboard solo or something else interesting for the keyboard part.

I’ve been wondering whether one way of giving myself an opportunity for a good keyboard solo wouldn’t be to rework the classic Toto song “Rosanna” into “Hosanna.” How hard could it be? Any thoughts on what the words could be?
