I had a random recollection yesterday morning, before I heard of Charley Pride passing:

In the early 1980s there were a chain of music stores called Sound Warehouse. I remember they were OKC based and had dozens of stores in the central US. Their owner was Dan Moran, as I recall. Dan Moran was killed in a car crash on the way to Will Rogers airport around 1982ish. Moran had told someone that he wanted 2 songs played at his funeral (I think it was just one of those observations in conversation), Danny Boy and Red River Valley. A record company executive for the central US knew Moran, and Charley Pride was on one of this person’s labels. Pride came to the funeral at All Souls Episcopal Church and sang.

Pride later said he never met Moran, but felt that Moran and he had helped each other prosper, so he was willing to sing when asked.
