Jermain Jackman at Winehouse gig
The Voice UK winner Jermain Jackman sang with Mitch Winehouse in the first in a series of monthly concerts to raise money for charity.
Mr Winehouse's first show at The Hippodrome in Leicester Square, London, raised funds for The Amy Winehouse Foundation, to help vulnerable and disadvantaged young people.
The 19-year-old follows in the footsteps of previous special guests such as Joss Stone and Mica Paris.
The Hackney-born singer, whose mentor was Black Eyed Peas singer Will.i.am, won a major recording contract after beating three other contestants- Sally Barker, Christina Marie and Jamie Johnson - in the final on April 5.
