In the CD's booklet, Richard Larsson - the original keyboard player - appears in the album credits in smaller letters, which, I presume, it's for the guest musicians. He played keyboards on tracks 2, 6, 11 and 12. A guy named John Lönnmyr played keyboards on tracks 1, 5, 7, 8 and 10. I made a quick research on google and I think he's the one who played at this show. Maybe he has been playing at this entire tour?
