Watch: Benedict Cumberbatch sings 'Comfortably Numb' with David Gilmour!

If you're a Pink Floyd fan or a fan of the television series Sherlock, this is the performance you should not miss for a pot of gold.

Actor Benedict Cumberbatch got on stage alongside rock n' roll legend David Gilmour to sing one of the greatest song of all times Comfortably Numb, at the Royal Albert Hall in London, the Rolling Stone reported. The concert came in the middle of the five concert series that Gilmour is doing at London in support of his album Rattle the Lock in 2015.

The former Pink Floyd guitarist and lead vocal stood by strumming his guitar, as Benedict joined in. 

While Cumberbatch did give up the mic to Gilmour for certain parts of the song, his performance came as a pleasant surprise to the audience, evident from the cheer that he got from the crowd.
