Yesterday evening saw night three of David Gilmour's concerts at the Royal Albert Hall - the middle show of five taking place this month to close the Rattle That Lock Euro tour - and an interesting surprise to those attending.

Those in the right position, and quite eagle-eyed, might have spotted a familiar face lurking in the wings stage right as Time/Breathe (reprise) began.

There was a healthy degree of shock and surprise to see the star of Sherlock, and one of the Star Trek films (amongst many other things) on stage for this song, and he seemed to have a whale of a time performing it. From David's official YouTube page, here's a video of Cumberbatch in action:
