I'm not expert enough to know the reasons why, but architect Lord Foster's Wembley design has helped to provide an outdoorvenue where the effect as Michael's vocals bounced around the stadium was rather like that of being in a modern surround-sound cinema.
Speaking of which, just blocks away from Laurelhurst Park is Pastaworks (3735 SE Hawthorne), the perfect venue to obtain all the makings of a delicious outdoor feast.
