Anime Question

I am trying to find an anime scifi movie from years ago. I thought it was Macross, but not so sure now. It involved an intergalactic war (I think) that had a group trying to get an ancient warship going and one of the group had to sing to get the ship going again. Originally, I thought it was Macross, but I looked through all the old movies from that series but couldn't find it. Not sure what universe it was in, may have been the Gundam universe for all I know. Anyone here have any idea what it might have been? I do know it was not Van Dread (sp?). Many thanks in advance
