Have the logo restored. Got our story view settings right so you can see most stories up-front without having to click 'Read more'. I got ambitious though and went a bridge too far; I installed a voting module and that whacked the new theme. I will have to try re-installing the theme tomorrow. In the mean time I set the site theme to the default "Garland" and that seems to have made it readable.
Thanks for bearing with me during this joyous "upgrading" experience.
