Steven Tyler performed "I Don't Want To Miss A Thing" alongside a Moscow street performer this past weekend.
During time out and about in the Russian capital the Aerosmith frontman became intrigued by the young busker who was performing the classic rock ballad to a handful of onlookers.
Footage recorded by members of the public shows Tyler intently listening to the busker before jumping in to lend a helping hand on vocals.
Aerosmith were in Moscow to perform at the city's Lubyanskaya Square as part of their now extended Blue Army tour.
