Tate's played in San Francisco twice in the last few months, so the opportunity is definitely there. I've no idea, however, how things went as far as turnout is concerned.
Regarding the set, I think they could stand to add a handful of songs, both new and old. With a catalog as large as theirs, there's no reason they shouldn't be playing at least two hour sets.
