Amy Winehouse for his first full concert along with the new band The Business International joined Mark Ronson on a stage show at London.

The 27 years budding singer sang its 2007' hit Valerie however she missed few of the words from it.

Ronson was playing a show at the 100 Club in front of the audience including the invited guests and the competition winners. Ronson said that he was very nervous to debut his new band in front of such a huge audience having great knowledge of music.

After playing tracks of his upcoming album, Ronson was joined by Amy for the second half of the gig. However the lady singer sang only the final track of that night.

Ronson is due to launch his new solo album named Record Collection, which is expected to release in the September.

Both of the artists have worked together for several times and tested the achievement but it's the time for only Mark Ronson but Amy came to support him. The upcoming album will be launched under the name of Mark Ronson and The Business International.
