nawww. it was their final show "for a while." an internet friend talked to Evan after the show and he said they're not necessarily done, they just don't know how long it'll be until they can actually take the time to put out another album and tour.
it's really not fair though. when Fun started, Jack promised us that he wouldn't let it interfere with Steel Train. and up until summer 2011 he made good on that promise. Fun played a lot of shows without him. it's the whole new album era that put Steel Train on the back burner.
