This remix was digitally released on iTunes by Atlantic Records on May 23, 2011.  J Farell first received widespread recognition on August 29, 2011 when his remix of Kreayshawn's single "Gucci Gucci" went viral on YouTube and gained over 7 million views in under 12 hours.  A week later, the video charted at #7 on YouTube's Top 100 Music Videos.  In 2013, Ed Sheeran spoke about J Farell's remix of his song The A Team with Ralphie Aversa on WPLJ's The Ralphie Radio Show.

The first video showed two sisters (referred to as the "Rohtak sisters" or the "Sonepat sisters") beating three young men with a belt alleging that the men had harassed them.  Soon, the video was being broadcast by television channels.  The girls were praised by the media and given the nickname "bravehearts".  After a second video emerged within a few days, which showed them kicking another boy, the opinions began to shift towards negative.  Six women claiming to be passengers on the bus had testified in front of the police.  They said it was not an issue of harassment, but a dispute over seats as the girls had been occupying a seat allotted to a sick woman.  A longer unedited video had been found on the internet, in which the girls asked a third girl, who had filmed the incident on their phone, to return it.  Later another man came forward and claimed that he had been similarly accused of molestation by the girls and he had to pay to have the charges dropped. <SEP>  In 2007, a 1998 video of "The 12 Days of Christmas", went viral with over 8 million views and subsequently led to a five-album record deal with Atlantic Records in 2008.  The YouTube video has been viewed over 20 million times.
