Before saying anything else, I have to say I know JP hates medleys (or so I've heard) and that they were pretty much a Portnoy thing to do, so I know this probably won't happen, ever. Even I'm not a big fan of medleys to begin with, just play the whole song and not small fragmets of many songs.
Having said that, what if, for fun, we imagine the scenario where DT are no longer celebrating the SFAM anniversary on tour and decided to include a TA medley on their set: what would it include? I imagine a 20+ minute thing would suffice. I'd like to give it a try, but I certainly don't have the audio editing skills to pull that off.
