The former Pulp frontman and his 12-year-old son Albert both live in the French capital, and Cocker reveals he flew into a panic when he heard gunmen were roaming the streets of the city massacring innocent civilians on 13 November (15).

Albert was visiting a pal's home as the horror unfolded and Cocker was unable to contact him until the morning after the terror attacks, which claimed more than 130 lives at restaurants and bars as well as a soccer game and a rock concert.

Cocker recounted his experiences in a spoken-word performance set to music, titled Friday 13th, 2015, which he debuted during his BBC radio show.

"I was going to bed when a friend rang and told me to turn on the TV," Cocker states in the piece. "I was worried about my son. I rang the friend's house but his parents weren't home yet. They'd gone to the theatre. I didn't want to panic them.

"I listened to the radio through the night. In the morning I rang the friend's house and my son had left to catch the Metro (subway) half an hour earlier. I worried. He arrived back safely."

In the musical piece, the Common People singer also describes the atmosphere in Paris after the terrible events and the floral tributes to the 89 revellers killed during an Eagles of Death Metal concert at the Bataclan theatre.
