There's a reference on Rocks off (http://www.rocksoff.org/Archives/07-19-2004/197357-1.html) that the performances were lip-synced to the original recordings, & a listen to the 2 tracks available on "The Early Rolling Stones Live 1964-67, Bulldog Records - BGCD 029" confirms this. So I assume the other recordings are similar in quality & not "live".
