A church records their service on audio. The service, open to the public but behind the closed doors of their building, is performed before a live audience who voluntarily attend. The church then sends out a copy of the recording to paying subscribers around the world.
The recording includes announcements, speeches, prayers, musical and theatrical entertainment, and a sermon all of which I would assume are copyrighted by the church entity since it is their employees and volunteers who made and produced it. Likely everyone who contributed gave consent to record their work, except perhaps members of the audience who were distinctly asked to pray out loud for the group's benefit.
Also included is the singing of gospel songs by the audience. The audience is prompted and led by a song leader who is possibly accompanied by a piano player on some or all of the songs. Assume the piano player is a paid employee.
My question is: Is the singing by the audience copyrighted as part of the larger or complete work?
Probably in the same category: Are the prayers solicited from the audience also copyrighted?
The question seems unclear in this regard: It is highly unlikely that the church asked any member of the audience for their permission to record their singing much less to distribute it. Assume they did not. No audience member signed a waiver granting the church copyright permission over their vocals, foot-stomping, or hand-clapping.
To further muddy the waters, some of the songs sung by the audience may be copyrighted while others are in the public domain. I assume the audience's singing is about common for a diverse group - so not necessarily "original" or "creative".
