Dude, don't even act like Stevie leaves the stage to give Lindsey the spotlight.
Back in the day, Stevie left the stage to do blow, change costumes, do her hurrr, get a drink of water, etc etc etc. I'm pretty sure now Stevie just leaves the stage so she can hear thunderous applause when she comes back in.
And why, exactly, would that coworker get the freeze when that coworker is the one that sculpted your song into a hit that generated extra radio airplay and, subsequently, a bigger check every month? That's shooting yourself in the foot. If I was Lindsey and dedicated so much more time in the studio.. spent time making something good out of a a scrap pile of vocals that Stevie just zipped in to unload quickly before heading out again.. I'd talk about the work
I did as well. There's a lot of "oh, Lindsey isn't working as a baaaaand" talk. I don't see why it's so easy to forget that Stevie has been nonexistant on other album sessions in the past. He's doing the biggest portion of the work and she gets to stamp her name on it and enjoy the majority of the recognition from the casual fans. I can understand problems with personality and stuff like that, but really when it comes to being involved, she has no room to talk.
