I've been looking at the Barb1/Bard as a better build than Barb2/bard, as it seems like only 1 barb level is needed to get a rage or two, sprint boost, etc. It seems to be a better way to get to warchanter faster (by level 7, i think), and the HP trade for earlier spell selection seems to be about right for the typical quest levels. Why bother taking a second level in Barb?
