Their two best songs are Calleth You, Cometh I and It Takes A Fool To Remain Sane (such a correct message). If you want more, I made a "best of" in the thread for that for Sergio who asked for one.
It's really a shame that they never hit big time international. With a little luck, I think they could almost be up there with the likes of Coldplay, The Killers, Muse in popularity.
