Hours after Friday's horrific terrorist attacks in Paris, Coldplay took the stage at Belasco Theater in Los Angeles for an abbreviated performance, including a somber cover of John Lennon's "Imagine."

Coldplay had been scheduled to live stream a big promotional show for their upcoming album A Head Full of Dreams, but the band announced shortly after the events in France that it would instead perform a short acoustic set.

As of Saturday morning, French officials have confirmed at least 129 deaths and more than 350 injuries related to the attacks.
