Correction to the Correction

For some reason, this kind of thing interests me.  The Reuters News Service put out a story around 9 PM (Pacific) last evening that included the following paragraph…

Allen, who is also a jazz musician and usually spends Oscar night playing the saxophone at Elaine's restaurant in New York, received a standing ovation from Hollywood's finest inside the Kodak Theatre and said, "Thank you very much … that makes up for the strip search" — a reference to the strict security surrounding the Oscar presentations.

Allen, who is also a jazz musician and usually spends Oscar night playing the saxophone at Michael's Pub in New York, received a standing ovation from Hollywood's finest…

Okay, first question: Who noticed the error and felt it was significant enough to warrant moving a correction?  I mean, given all the erroneous news stories that don't get corrected, why this?  Did Michael's Pub call up and complain?

Second and third questions: Doesn't Woody Allen play the clarinet?  And doesn't he do this on Monday nights, which are no longer Oscar nights?
