The pop-rap duo combined with the New York radio powerhouse to bring fun and music to the patients at New York-Presbyterian/Morgan Stanley Children’s Hospital. Jack Gilinsky and Jack Johnson, known to their combined 21 million social media followers as Jack & Jack, met in kindergarten. The pop-duo has written and published 16 songs, all of which hit the top of the iTunes charts in the week they were released. Patients had a chance to meet Jack & Jack and take selfies to post on their own social media channels. Z100 on-air personality Maxwell hosted the event.
