MAMAMOO has released a special version of "Mr. Ambiguous" for fans.
The girls debuted on June 19th, 2014 with "Mr. Ambiguous". As it's their 3rd anniversary today, they asked fans which song they wanted to see most, and fans voted for their debut song.
The girls went 'back' to 2014 and performed "Mr. Ambiguous", but the performance is actually a bit different from the original song. Check it out above! Can you spot the upgrades?
