Shane MacGowan's group stopped its set at Hyde Park on Saturday when a crowdmember suffered a heart attack. After Andrew Plank collapsed, a stranger rushed to his aid and performed CPR until paramedics were able to pull him from the crowd.
After the drama, the band returned to the stage and played one more song before ending the show. They later sent out a message to the victim via Twitter, writing: "The Pogues want to send out good wishes to the young man who had to be pulled from the crowd last night. Thinking of him & wishing him well."
Plank, 46, was taken to a London hospital and is now recovering, and the band is backing his family's search for the man who helped save his life.
The band has been retweeting messages from Lloyd Smith, who is married to Plank's niece, to back the drive.
The messages read: "Anyone know the name of person in crowd that performed CPR on the man who had heart attack at Hyde park? Want to say thanks... One stranger saved another's life... that person is a hero and should know it. Thank you."
The band's official Twitter page also features retweeted articles about the hunt for the good Samaritan.
