Brad Paisley is “in the zone” as his new single, “Southern Comfort Zone,” was delivered to country radio Thursday night.  The song was written by Brad and two of his friends and co-writers, Chris DuBois and Kelley Lovelace.  They were responsible for writing such big hits as Water, Online and Remind Me.  SCZ will be the first single from Brad’s upcoming album, although I don’t have a title, for the album yet, I’ve got the date.  Brad’s new album will hit stores on April 9th.  Brad’s Virtual Reality World Tour picks up Sept. 27 through the 29th in Florida.  He’ll bring the show to the 1-800-ask Gary amp on the 28th.
