From the New York Times online, a link on the front page (as it were):
The Smith's Music, on StageThat should be Smiths', plural possessive.
This goof and others (this one, for instance) suggest that writing errors are filtering ever upward.
Update: The error on the Times page has been corrected. Is the paper catching its (not it's) own mistakes? Responding to e-mail corrections from readers?
