BBC singing competition winner Jermain Jackman was in fine voice when he performed for students on Monday.
Jermain, who was the winner of The Voice UK last year, visited the King’s Lynn Academy and the town’s King Edward VII Academy.
The 19-year-old from Hackney was in Lynn to promote the National Citizen Service, which is run locally by the College of West Anglia.
Both of the academies he visited are part of the College of West Anglia Academy Trust.
Jermain, who took part in the youth scheme in 2011, is now an ambassador for the service and his role includes encouraging young people to sign up to NCS.
He spoke to students in Year 11 about the service, which is for 16 and 17 year-olds.
Andrew Gedge, the college’s service organiser and head of faculty for sport, public and caring services, said it was a wonderful opportunity for the students to hear from a celebrity who had completed the programme, which is designed to help teenagers to build skills for work and life and make new friends.
The next college NCS course will start on March 28. Mr Gedge added: “We believe that all young people can step out and step up to the challenge and demonstrate what fantastic, talented, able and committed people they are.”
