I'm really digging Broken Heart, it's a great song, it even has a guitar solo. The video is just icing on the cake. It's hilarious. I won't spoil the surprise but there is plenty of pay-off for sitting through a few minutes of watching these guys flail their arms around out of sync. It's great fun.
I've also embedded the video for Up All Night below. It's a good song but I prefer Broken Heart. Also worth listening to is their remix of London Bridges on their myspace page.
