Teacher Margaret Gabica got a big surprise on her last day at school on Wednesday when the pupils got together to do a flash mob in her honour. Today she's gone back to school to say thanks, after the video became an internet hit.
It was Mrs Gabica's last day teaching at St Julian's Primary School in Newport.
She was on playground duty - but in her 25 years at the school playtime had never turned out like this one did.
The other teachers had plotted a "flashmob" and as they watched through the staff room window the music in the playground started.
Rain clipping the far north through the evening but elsewhere staying dry with some sunny spells.
Public Health Wales figures show 25 more cases of the virus have also been confirmed.
Photos taken on Saturday morning show Roald Dahl Plass strewn with empty beer bottles and discarded canisters of laughing gas.
