Steven Tyler was checking out a Russian street performer, deciding to join the young man for a spontaneous duet.
The Aerosmith frontman stood by listening to the musician, with onlookers thrilled to see the singer approach the performer and join in on the fun.
The man was singing Aerosmith’s ballad from 1998, “I Don’t Want To Miss a Thing”.
The street performer was obviously surprised to see Tyler approach him and join him in a duet, but carried on like a professional.
Steven and Aerosmith have been in Moscow touring the city while documenting the trip on their Facebook page.
The band’s presence in Russia has thrilled fans, even giving a free concert at Lubyanskaya Square on Saturday to celebrate Moscow City Day.
This is not the first time Steven has surprised street musicians with a duet performance.
In May of 2014, he joined two female buskers in Lithuania that were playing Aerosmith’s 1993 hit “Crazy” on a violin and accordion.
