An Uplifting Musical Surprise for Dave Brubeck in Moscow (1997)

 

From Open Culture:

Ten years after his first visit to Moscow, jazz legend Dave Brubeck returned to perform before the faculty and students of the Moscow Conservatory. During his concert, an audience member asked him to improvise on the old Russian sea shanty “Ej, Uhnem.” About two minutes into the improvisation, a young violinist rose from his seat and started to play along. You just have to love Dave’s surprised look at 2:09.
