SRS: Those musical performances are recorded over even if the performer does their own singing; who knows what happens in the studio with the accompaniment.

RE: Levon Helm:
Martin Scorsese's The Last Waltz "...is hailed as one of the greatest documentary concert films ever made... In 2019, the film was selected by the Library of Congress for preservation in the National Film Registry for being "culturally, historically, or aesthetically significant...

...according to musical director John Simon, during post-production the live recording was altered to clean up "playing mistakes, out-of tune singing, bad horn-balance in the remote truck. Only Levon’s part was retained in its entirety." [wiki]

Hollywood unions and the taxman classify the Band & Staple Singers' performance of The Weight as acting. They are not portraying their 'authentic' selves. They, and the director, are 'recreating' a live stage act... that never actually happened... on a pro sound stage.
