There are many examples on YouTube of recording sessions where you 'see' comping being done but there's no reference noting it. Usually, the emphasis of the video is a more global subject like in
this link to Shania Twain and Lionel Ritchie recording "Endless Love". The recording session is portrayed for the viewer to feel the insecurities and struggles of Shania, so we see her sing a phrase, stop, and so on. But note the recording is being done phrase by phrase. It's not just due to her struggles because even when she nails a take spot on, she stops singing and recording stops. Each and every time.
