I love the end of the YMLF version included on Disc 2 of 2004 Rumours [Expanded], with Stevie singing “wonder why… feeling it’s time to try…”, instead of “it’s all I want to…”. I don’t know how many times she sang those lines live, but they are present in YMLF from the Rosebud film, so I’d say that’s my favorite.
