The 2012 CMT Music Awards are less than two weeks away, and that means fans will be able to see country superstars Lady Antebellum perform live on the show. Their performances are always a highlight of the CMT Music Awards, and it’s always a shame when they have to be archived — until now. Thanks to Lipton , CMT will open its vaults for the first time and allow fans to experience all of Lady A’s CMT Music Awards performances. But you need a key to unlock anything, and that’s where the fans come in. All you have to do is tweet the hashtag #UNLOCKLADYA from your Twitter account. Once we reach 5,000 tweets, we’ll add their performances to CMT.com, and you’ll get to relive those classic performances.
