Actuall the dates is right because I have the show and it is confirmed to be correct. "Pour Me," "The World Turned Upside Down," "Solid Ground," and "Ladder to the Sun," made their first appearances in 2003 on the last leg of the their AROBTH Tour. "Gravity" appeared originally in 2002 a few times as well. It is my humble assumption that some of these songs were originally on the first run of the album that was to be "X&Y" because if you remember an album's worth of material was recorded then scrapped, then new songs we written and recorded, which became "X&Y." Some of these other songs came out in the form of b-sides on the new album.
Gotta do the research man - go to http://db.etree.org
search under Artists and look through some of the recorded live bootlegs. There are so many songs played that have slipped through the cracks over the years.
