"Hey Everybody!" is the "title song" of this year's "I'm A Celeb - Get Me Outta Here!" show on German TV, starting 15th of January. This means the song gets at least two spins per show, before the commercial breaks.
In 2013, Lily Allen's "Hard Out Here" went to #2 on the charts and last year, "Break The Rules" by Charli XCX became a #4 hit.
They have two Top 6 albums in Germany, but no Top 30 hit to date.
