The BBC comments about Kayleigh’s stellar performance:
Kayleigh is one of 200 students aged three to 16 at Killard House School in Donaghadee, Northern Ireland … (she) often sings at the local Christmas concert at First Presbyterian Church, Newtownards, but this year she lost her voice and had to pull out of last Sunday’s service. Instead her headteacher played the video above, which had been filmed just weeks before at the school, and it left many of the congregation in tears.
