The Bravest, as Peace said. Also InOBU's song about Engine 33 - in this post with lyrics from the Mudcat CD Rose. (Scroll down to "Genie 01 Mar 03 - 06:04 AM" if it doesn't load at that post anyway)

This doesn't seem to be in the Digital Tradition, so far as I can see, which I think is a pity. It's a pretty good song.
