I first heard Superstar performed by Rita Coolidge on Mad Dogs and Englishmen (1970), followed by The Carpenters cover, and then Bette Midler's version on her debut album in 1972. Much to my surprise, all these years later, today I received an email from a well-informed friend with a link to Sonic Youth's cover above. Of all the versions I've heard, this is my new favorite.
It's the perfect requiem for Karen Carpenter. Listening to it makes me realize just how much I still miss her.
