No artist with the name "Roben & Knud"This error should never happen if you have clicked on a link in Chordie. I am working on fixing this issue. If you are getting this error and know that Chordie has a song by this artist and/or have clicked a link in Chordie: Please email email@example.com. Provide the url of this page and say you are receiving error #800. I will then try to fix the issue as soon as possible.
