The Greater Good as a single?
IMO, that could actually cross over. The duet between Gowan and Shaw and it being a softer song could get some airplay on AC radio. I know when people hear AC, they think "Oh no, not that. This is the new Styx and we want to ROCK!" Well, there is no outlet for true rock songs anymore and the only chance you have to get airplay if you are an older band is through AC where they may be receptive to a quality song. I've heard new Foreigner, REO to a small degree on AC radio and of course Journey struck it big with "After All These Years" off Revelation on AC.
Put some marketing umph behind that song and see if you can't continue the momentum on this album, because what ever numbers you want to look at - whether its my ranking on Amazon or the other rankings that Monker is putting out there, the album is starting to fade a bit and needs to be propped up if you don't want it to fade away.
Just some marketing thoughts....
