Jordan has already posted two videos (old videos, tho) of him practicing TCOT. It is unlikely, but what are the odds of them playing it on one of the two London shows for the live recording?
About one year ago Jordan posted short clips of practicing PBD weeks before the start of the DOT Tour and especially since then I always have the impression that such clips are meant to contain a hint which pieces will be performed in the near future. So I suppose the chances of seeing TCOT live as an encore in London (maybe AWE on the first night / TCOT on the second night?) have now increased slightly.
Additional arguments in favor of playing TCOT could be:
- I read that some fans expect them not to play the same static setlist on two following nights (especially for a DVD recording (just like at Luna Park))
- it is an epic (not a fan favorite though (I remember the "rank the DT mega-epics" poll where it did not get a lot of votes), so it is perfectly made as an encore
- it never has been used for a DVD / pro shot recording (which is likely to be the strongest argument?)
- I guess it is not too demanding for James (??)
- they already played it with MM before, so less practice is needed (compared to Octavarium)
Overall I still think it would be a big surprise to see them performing it in London but you'll never know.
