Pixie Lott performs special gig at school assembly

Students at Ravens Wood School in Bromley got a fantastic surprise today when Pixie Lott dropped in to assembly.

The pop star, who grew up in the area, performed three tracks. But the real reason for her visit wasn't to promote her new single - it was to support a campaign calling for compulsory cardiac screening for young people.

Every week, 12 young people lose their lives to sudden cardiac death in the UK. And 80% of them have shown absolutely no previous symptoms.

Just three years ago Ravens Wood School lost one of its own pupils to sudden cardiac death. Ben Daniels, 15, collapsed without warning while playing football in 2011.

His father Paul has now set up a fund to pay for other students at the school to be screened for heart defects.

And he's confident that Pixie's visit will drive home the importance of screening to Ben's contemporaries.
