I'd heard this through unofficial channels, but when They Might Be Giants announces a release date for their latest DVD/CD set in their newsletter, I think it's safe to say that it's official now: Here Comes Science will be in stores in September. As they put it, "the periodic table, photosynthesis, the color spectrum, the scientific method, paleontology--no topic is of [sic] limits in this freewheeling collection of songs!" Well, that sounds fun (if not entirely grammatically spell-checked).
Still not a fan of that title, but I guess my attempts at convincing them to change it via mind-control failed.
