TEACHERS at Sacred Heart Primary School have been at it again. 

After going viral last year with their Carpool Karaoke video to say goodbye to year 6 pupils, the Warrington Guardian School of the Year 2018 have been making sure youngsters left with a smile once again this summer. 

And they have clearly put the time in with this year's effort. 

Staff sang along to some of the biggest songs from the hit film The Greatest Showman during the video as well as performing dance routines and even attempting to floss. 

You can watch the video in full by clicking the tweet below or watch our highlights in the video above.
