lets just say I know what I'm talking about, I had a girl & a guy lead singers in my 7pc band for 20+ years ......I also had a duo with a girl for years also KB/Guitar......now I was lucky and had minimal group problems,......but last 17 years as a Power Single and I wouldn't trade it for the world..as I said if you can't sing lead all night then get someone to do it girl or guy....but, be prepared for all the consequences, financially and personally....have fun.
