In 2013 Ghost changed their name to Ghost B.C. in the US, citing legal reasons which were undisclosed in a press release. One possible reason for the change may have to do with the other Ghost, the long-running Japanese rock band.
The real names of the band members have so far not been revealed, but Tobias "Mary Goore" Forge of Repugnant has song and lyrical credits under the pseudonym A Ghoul Writer, according to (Swedish Performing Rights Society).
Opus Eponymous was voted as the third best album the year 2001-2010 by the readers of Sweden Rock Magazine.
