It was literally a 'blink and you'll miss it' error on Strictly Come Dancing that saw Tess Daly apologise to viewers during Saturday night's show.
Dan Walker and Nadiya Bychkova had been performing a Charleston from the musical Singing in the Rain when the screen suddenly went blank.
It prompted people across the UK to wonder if there was a problem with their TV, until vision returned a second later.
After the dance was over - the final performance of the night - Tess turned to the camera to say: "I'd just like to apologise for a slight technical hitch during that."
The show saw Cynthia Erivo join the judging panel to replace Craig Revel Horwood for musical week after he tested positive for Covid-19.
The Oscar nominee and Broadway star was welcomed onto the show with a collage of her career highlights.
The show’s co-host Claudia Winkleman said: “Craig is not with us tonight, he’s tested positive for Covid-19 but he’ll hopefully be back next week. We will miss you so much, Craig.
Fellow host Tess added: “Keeping Craig’s seat warm this weekend is a star of stage and screen who has Tony, Emmy and Grammy awards to her name.”
The actress assisted in judging the dancers on their musical performances alongside Motsi Mabuse, Anton Du Beke, and Shirley Ballas.
