 :I'm sorry, but I cannot agree.  If it's not a reliable statement when it was made in the IMDb biography, how can it become a reliable statement just because some newspaper copies and pastes it from IMDb?  Since the IMDb biography predates the Pure Mirror article, it's indisputable that the statement originally appeared on IMDb, and was simply copied from there by the Pure Mirror article (without attribution).  An article with demonstrated plagiarism cannot be taken seriously, regardless of where it is published. (Especially when it plagiarizes from unreliable sources!) 

 :::There are thousands of news reports & magazines reporting NFAK's 6-ocatve range. 

 :If so, one or more of those should be used as the source.  However, one needs to be careful about eliminating Wikipedia mirrors.  (I wouldn't be surprised if all of the sources for the 6-octave claim turn out to have copied material verbatim from some past incarnation of the Wikipedia article.) 

 :Please also see the previous discussion on the Talk page ("Six-octave range?"), where the editor claims that a 6-octave range is physically impossible.  This is the supporting quote: "Storms also holds the Guinness World Record for the widest vocal range for a male. His records have been published in the Guinness World Records 2006. He broke both of these records in August 2008.[1] He is able to reach a full 5 octaves below Middle C and reach a sound of just 8 hertz which is inaudible to the human ear. The previous record was 16.5 hertz, just over a full octave higher.[4]"
