There's something endearingly old fashioned about Vampire Weekend, and Cape Cod Kwassa Kwassa starts as if imitating 1950s calypso.
It turns out the opening hook is the subject of a sort of round, the type you might have sung at first school, and its innocence adds charm to the track, built on further by the breezy vocal.
The band have become a live favourite in their UK festival appearances this summer, and this adds another string to their bow - surely final confirmation that their debut album should be sought out if you haven't done so already.
