The impressive sum was paid by a mystery Russian businessman for Amy to give her first full performance in two years at a show in Moscow on Friday (19.12.10).

The 27-year-old singer, who has famously battled alcohol and drug problems in the past, was flown from London to the Russian capital to perform in front of guests including billionaire businessman Mikhail Prohorov and Sergei Kapkovym, head of the Russian Football Association.

The `Rehab` singer`s popularity has soared in Russia after it was revealed her grandmother was an immigrant from the country.

Although she reportedly seemed uneasy as she took to the stage in a leopard print dress and launched into opening track `Cupid`, a friend said Amy was thrilled to be singing live again.

The source said: "It was a fantastic performance. Amy was brilliant and went down very well with the crowd. She has a real following in Russia and no one was disappointed judging by the reaction she got.

"She is clearly glad to be back on stage. 2011 is going to be a big year for her."

Amy flew home shortly after the private concert but her return is set to continue with a series of six shows scheduled for next month in Brazil.
