New Yorkers have become accustomed to spotting celebrities throughout their city, but it generally results in casual rubbernecking and maybe a clandestine photo op if the moment is right. But imagine getting a private performance from Macklemore and Ryan Lewis while riding the Bx6 bus. A lucky group of commuters experienced just that when the rapper-producer duo hopped on to perform their hit "Can't Hold Us" as part of the Grammy Awards' "Music Unleashes Us" campaign.

The surprised bus riders are at first dubious as Macklemore and Ryan Lewis pull out their boombox, in fear that their commute will soon be interrupted by noisy performers. By the time they understand what's happening, everyone is on their feet enjoying the moment.

The duo will perform at the Grammys on Jan. 26. They're up for seven awards, including Album of the Year, Song of the Year and Best Rap Song.

Watch the impromptu performance below.
