I would say that musically, the TRD tour has been replaced by the KTGC tour :
2008 setlist had more TRD tracks than KTGC tracks :
up to 5 at Amsterdam : WAM, HFB, MT, DGTK, DB
I am listening to 2008 stuff by now, and I think that the 2003 tour would have sounded this way, but of course it's just speculation.
Marks obviosuly wanted to play some stuff from TRD.
after the 2003 tour deleted, what could he do ? plyaing this sruff on 2005 tour, but it would have dropped some stuff from Shangri-La, which he obviously didn't want.
then in 2008, it didn't bother him to drop stuff from KTGC in order to play stuff from TRD.
in 2010 he went back to TRD again with Coyote, and kept HFB.
the TRD album is obviously one of his fav, while KTGC is not...
