Are they really supposed to be singing to Jesus, and they are up their fighting.   Although it looks a bit staged now, I remember some used to fight like that (in slow motion), not in the church, but in the world. Most often the former gospel  quartets were know for their great harmonies, choreography( to closely match secular groups  i.e. the Temptations), ability to travel around for evening services,  showing off  their loud(colored) suits, finger rings and running the women. It was a show more than anything of knowing what they were singing about. It is such a disrespect to act and behave as these individuals in the video, let alone praying before their rehearsals or stopping to realize where they are.  According to the person who loaded video, the drummer is 48 year old , and he is beating up the 77 year old lead singer.
