My sister's father-in-law died and her mother in law is battling covid. She wants a song sung at his funeral but just can't think of the name of it. The word she can remember is something like I want to wake up some bright morning with the sun shine through my window or something similar. He was an elder in the church. I've tried Google search and I can't find anything. Does anyone have any suggestions?

A family friend heard an elderly man sing song at a funeral. He asked if I knew or could find the actual title and words. I have had no luck. He said he thought a few of the words were " my old gray haired mother'.
