Groove Thing wow judges as they dance into Britain's Got Talent

Twelve-piece dance troupe Groove Thing from South Wales had the Britain's Got Talent audience on side even before they said hello - and their 70s-inspired routine certainly impressed the judges.

Groove Thing hail from Port Talbot and they are already on tour, performing at local schools this week.

The group is made up of children aged 7-11 - primarily girls, with just one boy, Ben, who apparently "gets lots of attention"!

Watch; Dean Thomas catches up with Groove Thing back at school in Port Talbot:

The troupe are now through to the next round and are training almost every night.

BGT judge David Williams described their audition as "brilliantly entertaining".

Simon Cowell said that every one of the young dancers "gave 110 ten per cent", while Alesha Dixon said "I love you guys".
