A toddler recovering from brain surgery received a private performance outside his window from members of The Dropkick Murphys.

Three-year-old Quinn Waters, from Weymouth, MA, recently had surgery to remove a brain tumor and then a stem cell transplant. He has to stay at home while he recovers and can only interact with non-immediate family through his window.

So far, he’s received a long line of visitors at his window, including dancers, police officers and a puppy parade, CBS Boston reports. The Dropkick Murphys were his latest visitors, and the video of their surprise performance has gone viral.

The video of the special performance has received over 40,000 likes, even one from Tom Brady.

The Waters family says people can help by donating blood or platelets at Boston’s Children’s Hospital’s Blood Donor Center.
