John's (ie, "fredfish's") advice is equally applicable to other images relating to Lois Lane, and perhaps, even the name itself. There is an excellent chance that some company holds the copyrights to such things, and should your band succeed beyond your wildest dreams and then appear to the world to have deep pockets, the copyright holder might come knocking at your door.
As John suggested, it's so easy to come up with your own logo, name, etc., just take care of this now rather than trying to fix the problem after the fact. Of course, the reality is that if the success of your group is limited, the copyright holders would likely have zero interest in you (ie, because no money would be available from you) unless you were doing something to hurt the image of Lois Lane (ie, decrease their other revenue streams).
As you may have picked up on: IT'S ALL ABOUT MONEY.
Just a thought,
