Radio Tango

Radio Tango was a Rock station in Oslo, Norway.  The writing translates to "Bold Music, Great Radio."  These website postings from 2008 mention that the Norwegian Media Authority was on the verge of revoking Radio Tango's license.  This seems to have happened as there is no online presence for the station that I could find.
