I loved the Flight of the Conchords show when it was on TV, so I was overjoyed when my husband showed me this. It's the long version of their new charity song, Feel Inside (and stuff like that).
They're meeting with Murray and hoping for a new gig before heading off to talk to kids about what it's like to be sick and how to help sick kids. The video ends with the song, performed by the Conchords and quite a number of other people. It's catchy and the video itself is pretty funny - if on a serious topic.
