Can someone identify this piece?

Dear friends!

I received a message today from Dan who seeks helps in identifying this piece:

"Hi Vidas, do you have any  idea what this piece is here?  This recording is taken from some recordings that were  done at the school for the blind that we have here in the town where I’m from.  I’d went there until 2006, and got my start in organ there in 2004.  This is the same organ that I’d started out on, a 1961 3-manual Casavant.  This recording, I think was done sometime in the 1970’s."

​Here is this piece

Do you know what it is? Dan would surely appreciate your help.
