Amy Winehouse will be joined by Specials star Jerry Dammers during her performance at the Nelson Mandela concert in London tomorrow (June 27th), it's been reported.

Winehouse and Dammer's are expected to perform 'Free Nelson Mandela', which Dammers originally wrote in 1984 against Mr Mandela's imprisonment.

The original version of the song was performed by the Specials and reached number nine in the UK charts.

Winehouse's appearance tomorrow will be her first public performance since it was revealed that she had traces of the lung disease emphysema in her body.

The signer fainted while “doing admin” at her home in North London nearly two weeks ago and spent a week in hospital under observation.

Other acts scheduled to perform at the concert tomorrow include Leona Lewis, Razorlight and Queen.
