I'd have to look up how many times (if ever) Sherlock actually told John Watson that "the game was afoot" at an adventure's commencement. Watson may have occasionally said something like "Another Mystery Solved," at one's conclusion. Or perhaps not.
I definitely got a song written and recorded in the current Song Fight, though. It's a bit Christmassy and a bit weird. It's a cheating song and a waltz. It's got Mellotron and sleigh bells going on.
[A slightly reworked version of this track will appear on my forthcoming Christmas EP. As such, the Song Fight version has been removed from SoundCloud. Perhaps I'll remember to re-embed this song in December?]
