Insider is all about how live entertainment has the power to bring people together, and we just couldn’t pass this one. The choir at St Joan of Arc Catholic Primary School had been rehearsing Guy Sebastian’s hit song Choir for their school performance. 

Halfway through the performance, Guy Sebastian busted through the auditorium doors to take the lead. In a wave of surprise, students began screaming and crying with excitement, whilst Guy continued like a true professional.  

Once the students had calmed down (well most of them anyway) the entire school and Guy finished their performance in a strong unison.  

You can check out the video of Guy’s choir surprise below, a truly moving moment.
