RobbieJ, your discussion of the segment and your reaction to it are so much more interesting to me than Cocker's rendition. I can only say "thank you" for the entire discussion.
(And, again, I am sorry you thought I was accusing you of insincerity. Not a chance.)
Rewatching this right now, I'm finding Cocker singing I'm Still here no better or worse than Stritchie singing it at Sondheim's bday celebration. The visuals of the women are even more compelling than I remember, particularly during the final few bars of the song. And people did get introduced to the "proper" way to sing by the song with the initial excerpt from Yvonne DeCarlo.
Struck again by how fast this documentary moves. Really keeps you engaged. Love it. The story about the editor of the doc gives insights into how it was all pulled together.
Feel free to substitute "accept", "appreciate" or even "understand" then.
Nobody has argued that "I'm Still Here" is sacrosanct and only open to one interpretation. For some of us, however, it remains an open question what Cocker accomplished or even intended to accomplish.
