SAVANNAH — Gregg Allman agreed Tuesday to drop his lawsuit against movie producers who were making a film about the singer's life when a freight train plowed into their Georgia crew and killed a camera assistant. Attorneys for the Allman Brothers Band singer and Unclaimed Freight Productions told a Savannah judge Tuesday they reached an out-of-court agreement a day after Allman's lawyer grilled film director Randall Miller on the witness stand about the Feb. 20 crash. Attorneys declined to discuss details of the deal, including whether Miller would be able to move forward with reviving the "Midnight Rider" movie.
