The 39-year-old rocker surprised the homeless people at The Bowery Mission in Manhattan by jamming with them, reported Femalefirst.
James Macklin, the mission's director of outreach, said Martin's appearance, which included performances of songs like The Beatles' "Yesterday", Prince's "Purple Rain" and David Bowie's "Life on Mars?", helped lift the spirits of the homeless men and women at the shelter.
"Chris Martin proved once again the power of one person to make a difference through The Bowery Mission. As the temperatures drop and we serve thousands of lonely people during the holidays, Chris has lifted our spirits today," Macklin said.
