This may be relevant...Bessie Jones and I used to share stages together, from early sixties into seventies, and we used to do play-party games- she'd sing hers and I'd sing one from our family that matched it. She had many "shout" songs, and always explained that the word, "shout" in a game or song meant, "dance." Younger members of her family and community would sometimes be with her, and as she sang they'd sing with her, clap hands and dance or "shout."
