Well, since he's already hiring musicians to learn and perform 50 minutes of complex music, it would be kinda a waste to perform it only once... so it makes sense to play not a full tour but just few dates here and there to justify the effort of learning all that material.
Of course he is not over DT, but then again, it's his big party, he wants to celebrate his carrer, DT was a part of his carreer, he wants to play the AA Suite, hence we return above... since he's making other people learn it, they could do something else than a one-off gig with all the effort required.
