The Baker Street Boys

Characters (c) Moffat, Gatiss, Cumberbatch, Freeman, Graves, Conan Doyle's Estate, Rascal Flatts
Concept

Based on this post that I saw ages ago on The Science of Johnlock.

Technically, the joke is supposed to imply the Backstreet Boys, but I saw the picture of the boys, and this album immediately came to mind.

I've been meaning to do this for what feels like eons, and it did, indeed, afford me some amusement.
