Jimmy Somerville, frontman of 80s British synthpop group Bronski Beat, was randomly walking his dog down the street in Berlin when all of a sudden he came across a street performer singing his 1984 hit, "Smalltown Boy." 

Somerville listened for a while, and then decided to join in.

At the end of their duet, the stunned street performer asks, "Is it really you?" to which Somerville replies with a sly smile, "It's me."

And the whole thing was caught on video. Watch the epic duet below (Somerville joins in at :25).

Now watch the original "Smalltown Boy" music video:
