22. And the final reason why O.B.A exists, with audience participation

Audience participation starts about 9:40 into the video.

From none other than TED Talks.

In 2000, Tim Rhys-Evans set up a Welsh male voice choir called Only Men Aloud, a contemporary take on the Welsh choral tradition. Eight years later, it was voted the nation's favourite choir when it won BBC 1's Last Choir Standing. In 2010, as part of his mission to safeguard Welsh singing traditions, and to keep choral singing alive in the communities in which it first developed, Tim formed Only Boys Aloud. It's open to all boys between the ages of 14 and 19, without audition, and there are now nine separate choirs, in nine South Wales towns. Together they form Only Boys Aloud. Mentored by the adult members of Only Men Aloud, part of Tim's mission is to inspire the boys in other areas of their lives and one way he does this is by providing unique performance opportunities, such as TEDxObserver.

A message from each and every Welshman to each and every American, as long as you go all the way through this last video.
