Aerosmith frontman Steven Tyler staged an impromptu performance on the street during his visit to Moscow.

Tyler, who was in the country with his band to perform at Lubyanskaya Square to celebrate Moscow City Day, joined a street musician to jam Aerosmith's single "I don't want to miss a thing".

After the song was finished, Tyler gave the street performer a high five, put his hat on the fan's head, and then posed for a picture together.

The crowd gathering around them cheered and shouted 'Thank you' in Russian to the star for his surprise performance.
