Bobby McFerrin improvising in real time and having the audience follow; not accompaniment-based, but more of a call-and-response activity.
Bobby McFerrin's "Say Ladeo" performed by CASMEC's 2017 Vocal Jazz Ensemble (I'm in here!!)
The entire song is pretty much a circle song, but the director, Roger Treece, incorporated a live, improvised circle-singing section in the middle (starting at 03:53) with some improvisation in the high voices created by one of the soprano students.
