A song so good they played it twice

Hello, hello! The guys at the @U2 blog report that U2 played Vertigo TWICE at tonight’s concert in Seattle. Instead of bowing out with ’40’, as they have been doing so far on this tour, they repeated their hit single, as if they were a young band on their first tour and ran out of songs to play. How. very. odd.

Update: reader Shaun suggests they may have been filming the song for their Good Morning, America appearance.
