Thousands of music fans packed out Sheffield Arena on Saturday night for the first leg of the Smash Hits Poll Winners Tour.
Biggest screams for Blue
It was the first of nine dates leading up to the Smash Hits Poll Winners Party, the poll where you get to vote for who you think has been the best this year.
The biggest screams of the night came for final act Blue, but the line up included music from loads of different types of artists, from Pop Idol reject Darius to garage maestro MC Harvey.
Harvey told CBBC Newsround Online what the atmosphere was like on stage.
"It was brilliant - loads of kids on half term just enjoying themselves," he said.
'It was wicked'
The tour will come to an end on Sunday 24 November when the winners will be announced at London's Docklands Arena.
