The Old Man S 01 E 05

Usually when I watch a recorded episode I cut and stop when the end credits start (to go to the next episode, if I have it). However, this time a very beautiful melody with marvelous vocals from soloist and choir had started before my stopping and I stayed on till the episode ended in full, just to hear the music. And what was the music? No clue could I find trawling the end credits, the IMDb page, trivia and rewiews. I would be so grateful if someone knows the name and posts it here or sends to bkb.ulrich@gmail.com. I certainly want to hear more of it.
