While researching the Swon Brothers, I came across this video of Colton Swon actually auditioning and making it through to Hollywood on American Idol Season 7.  It appears that he did not make the top 24 of Season 7 on American Idol, but interesting none the less, since he and his brother were on "The Voice" tonight 5 years later.  

Tonight Christian singers,The Swon Brothers, were on the show.  They are brothers, Colton and Zach Swon from Muskogee,Ok.  They grew up around music, parents were in a southern gospel group and played in several churches growing up.  They performed the song "American Girl".  About half way through their performance it looked like no judges might turn around.  However, at the end of their performance both Shakira and Blake Shelton turned around.  They had the funny line after they sang, they told the judges and audience, "you have just experienced your first 'swoncert'.  Of course, they ended up going with fellow Oklahoman, Blake Shelton, to join his team.  

Stay tuned to "The Voice" on NBC to watch the Swon Brothers in the "battle rounds".
