Looking for the Bach's While Sheep Safely Graze, arranged for cello solo since I don't expect to find a published version for trombone solo.
Prefer organ accompaniment instead of piano but will take what I can get.
I expect this would be public domain but don't mind paying for an arrangement.

You can find several versions on IMSLP.
Hope you find one that suits your need.

Excellent, thank you
