Music group Buya plays on Blue Line train car

CHICAGO (WLS) -- Some CTA passengers stepped onto a Blue Line train and into a party.

Passengers were out of their seats and up on their feet when the group Buya began playing last Tuesday night.

Teo Lopez recorded this mobile party. He says the video has gotten a lot of attention since he posted it online. And according to him, this is the second time the group has performed on a CTA train.
