I'm so glad she's doing better! I don't have a problem with her going forward with the tour, if she's able.
HOWEVER, I do think this should be her last major tour. It's too much on the body.
The demo version is all I ever listen to! I must admit I'm a sucker for a Pharrell production.
I'm also the same way with Living For Love, I've heard the final version maybe twice. I always listen to the demo version, so much better!
