It's the star's first full live UK show since he had to cancel his UK 'Symphonica - The Orchestral Tour' last year after contracting pneumonia.
The singer is now back in good health and is beginning a tour of the UK with an orchestra.
George Michael will be performing a selection of his own songs, from a career that has spanned nearly 30 years.
Some songs have been re-worked and re-arranged to make a more classical sound.
Organisers have confirmed that tickets for last year's concert, which was cancelled, will be valid at tonight's show.
