Two men compete in incredible sing-off on Chicago bus

An incredible sing-off between two men on a late night Chicago bus ride has gone viral, after a video was posted online by a fellow passenger

Brianne Downing was riding on the bus last week when a man burst into song.

She started to record the performance because his voice reminded her of Titus Andromedon from the Netflix comedy Unbreakable Kimmy Schmidt, Ms Downing told The Daily Mail.

He sang ‘His Eye is on the Sparrow’, a song recorded by artists including superstar Whitney Houston.

When he finished singing, a second man began to sing ‘Mattinata’, an Italian classic composed by Ruggero Leocavallo.

Ms Downing posted the video of the performances on her Facebook page, and it has since been shared more than 225 times.

“Tonight's late-night Chicago Avenue bus ride was AMAZING,” she wrote in her post.

The two men ended the friendly sing-off with a hug.
