Ooh, yeah...interesting...perhaps, a couple of years after the JLA kicked the bucket, she was feeling a bit down, so Arty persuaded her that she needed to sing a bit of karaoke to cheer herself up. Obviously, she knocked it out of the park and got rapturous applause, which made her feel better. About this time, she was starting to run out of money and was looking for a job, and Arty had the idea of hiring her out as a Lookalike/Impersonator Performer. M'gann was dubious but went along with it...and then started up a small website to try and turn it into a lifestyle business. :D
