So, according to GMTV, Imogen Heap is not known well in the U.S., which seems crazy, since you can't watch CBS here without hearing one of her songs (or seeing a NCIS spin-off). But then again, toothbrushes aren't well known there either, and we've had those for like, 10 years here (I hold a Masters in Easy Jokes about English People Who Are in Fact Very Nice). Apparently Imogen is looking to storm the U.K. now, so she performed "First Train Home" on GMTV in a stirring performance that is typically ethereal. Calling her clapping her hands "cute" at the end would be underselling "cute." [Culture Bully]
