Speaking of Zeppelin, weren't most (or at least at first) of their alubms 1,11, 111 etc? I don't even remember the title of the one album I have. The old man with hay/straw on his back with a mountain background if I'm not mistaken. I don't think there's a title on the cover. It has Black Dog, Immigrant Song, Stairway To Heaven on it. Lots of great songs.
