I was flummoxed for a moment
Surely it was what we once used to call a Negro Spiritual, but would probably these days call Gospel?
There was quite a lot of communal singing in my childhood, often unaccompanied. We used to do a lot of it in the car, with my parents, who I think particularly learned the habit during wartime army service
And then there were Brownies & Guides. Singing round the campfire (literally) or at the close of every meeting. Spirituals were a particularly popular part of the repertoire
