Watch These Kids Deliver the Best Surprise to a Teacher Battling Breast Cancer

The kids in the chorus at PS 22 have an annual tradition for their last practice: they perform a song with their director, Gregg Breinberg. But this year the Staten Island elementary school choir went for a tearjerker, singing Martina McBride’s cancer-anthem “I’m Gonna Love You Through It” to a teacher recently diagnosed with breast cancer.

Teacher Adriana Lopez, who can be seen in the video watching the group of fifth-graders serenade her from a seat on the bleachers, was wise enough to bring a wad of tissues to the performance.

This isn’t the first time the PS 22 chorus has gone viral pulling on our heartstrings: their popular YouTube channel, which now has close to 70 million views, featured a tribute to the the victims of the Sandy Hook shooting back in 2012.
