Been playing through the Hello, Dolly! transpositions book. Oy!
I grew up with Channing’s keys, and they are in my blood. As far as listening to everyone else singing it, I learned long ago to just turn my senses off to the new keys and modulations and just go with it and enjoy. But sitting down and playing them? It’s almost like reading new music.
The book looks fine to the eye, but the body is rejecting the donor notes. And beyond simply having to relearn some of this, a greater appreciation than ever has grown for the likes of Robert H. Noeltner, who not only gave most of it to you, but in a way that still made it happen really well at the piano.
