Bono. Does. Not. Stop. His artisitic ability is feuled by his passion for philanthropy...and his latest release is no exception.

If you are a U2 fan, you will not want to miss this. In anticipation of the re-release of the band's classic album The Joshua Tree next week, Bono has posted a personal message on the Web, singing and talking us through - "Wave of Sorrow." It's a track that was created during sessions for the album in 1987.

Here is a rare glimpse at someone who is widely regarded as one of the most influential musicians in history. And gasp! Even he forgets his lyrics!
