What if Sherlock woke John up at ungodly hours of the morning by playing ABBA on his violin? 

‘Sherlock, is that.. Is that ABBA?’

‘Come, Jawn! We are Dancing Queens!’


‘Friday night and the crime’s are low,

Lookin’ out for a scene to go.

Where they find the right body, getting in the swing,

You’re on the look for a crim.

Anybody could be that guy…

Night is young and Sherlock’s hiiiiiiigh.’
