"If it ain't fun, don't do it"!!! A wise man once said... Sounds like the lady in question just might be putting a dent in the fun factor with this band. Personally, I'd take a pass but, that's a decision we can't help you make. We, my band, recently acquired a keyboard player. Dude is the real deal, has nationwide cred. Now we are a bar band probably more like a Dad band (great grand dad in my case) straight outta the garage. So this guy shows up, hands out sheet music. None of us can read. I got a bit testy at first , cause I'm old. But, he was really cool about it. Brought me sheet music with bass tab and sang my parts so I could get the timing down. And, now we are off and running, getting into some complex tunes and becoming a much much better band. So, back to your lady BL.Have a face to face over drinks, coffee, tea, whatever. See if there's any chemistry (musically that is) on go from there. But, have fun Bro!! life is short...
