No mystery here; this "Sherlock" musical is awesome.
YouTube team AVbyte produced a musical version of Sherlock and Watson's reunion after Sherlock's apparent death at the end of last season.
The actors in the video above not only possess great singing voices, but they also have a remarkable resemblance to "Sherlock" stars Benedict Cumberbatch and Martin Freeman.
Can the West End debut of a "Sherlock" musical be far off?
The new season of "Sherlock" premieres this Sunday, Jan. 19 on PBS.
