Loved them all across the decades but my DS favorite is Once Upon A Time. For MK solo period I pick Border Reiver. However, LAJADAS would be a clear winner had MK decided to go with it on the last tour. When I first heard Tracker I immediately thought this would be the perfect concert opener. It has all necessary ingredients: a quiet drum /bass intro with a few teasing tasty guitar licks that could be played from behind the curtain (or still in the blackout) and then all the band joins in for the grand opening. Good tempo, not too quick not too slow, nice opportunities to show off and improvise, could go on forever like RATR or Calling Elvis did in the past. I don't know why they didn't go with it. It was a no-brainer. Lost opportunity. Unless they open with it on the next tour, that is.
