Lee Greenwood announced his imminent retirement last year, so perhaps this is a passing of the torch? The country legend is teaming up with viral country singer Drew Jacobs on a newly reimagined, more rock-centric take on Lee's classic "God Bless The USA." Jacobs gained Internet renown for his rockish takes on country classics, like "The Thunder Rolls," by Garth Brooks, "God’s Country" by Blake Shelton, “Whiskey Lullaby” by Brad Paisley & Alison Krauss, and others. The song officially drops Friday.
