Pictures from a fan account on Instagram:
The rest of Delhi, who didn't happen to be partying at Summer House that night, has been left heartbroken and bereft:
I sleep for a bit & Chris Martin plays a secret gig at a Delhi bar! I should not sleep incase rockstars invade bars & kill people with swag

This is going to be a sleepless night tonight. CHRIS MARTIN IN DELHI. WTF. To do list : 1. Start going to bars.

CHRIS MARTIN IS IN DELHI OH, MY GOD. I'M CRYING. I HOPE THIS IS A SIGN THAT @coldplay IS COMING TO INDIA. OH GOD PLEASE PLEASE PLEASE.

Of course Chris Martin had to be in Delhi. Of course, because my life just couldn't get more unfair.

Timelines on Twitter are now filled with pleas to Chris Martin to come play in their city, like this one:
Hey Chris Martin, you don't know what you're missing by not performing in Mumbai! (Read: PLEASE COME TO BOMBAY AFTER DELHI PRETTY PLEASE!!)

And also jokes, like this one:
That awkward moment in Delhi when Chris Martin is going home and there's a power failure and there are no lights to guide him home.
