From BreathHeavy so take with a grain of salt I suppose:

So what do you guys think?

Is Britney capable at this stage of her life/career to pull of mostly live and energetic performances night after night for an extended period of time, considering that hasn't been the case the past couple tours?

Do you think it's even right to ask that much of her or is it too much?

LMFAO. I highly doubt this is true because if it is this deal is never happening because there's no way Britney will do a whole concert live.

And Celine lip syncs all the time as does Shania, let's not act like lip-syncing isn't a common thing for a vegas act.

The show can't be lackluster though, it won't work if she doesn't bring her A-Game.

No.

Pre-recorded vocals and like 2 songs actually live will do the trick.

But no one doubts Celine or Shania can still sing live though.

For $100M she should sing live for most of the show. I'm sure they'll do something where she strips down some performances and sings live.

Not happening.

She just needs to use the same back-track techniques that Beyoncé uses.

I don't want her to have Vegas Residency why would any of Brits fans want her to do that

Britney will do like one song (a ballad) at most live. Let's just accept that now and move on.

That's what she's been doing for the past 10 years and what she will continue to do. Her vocals are pretty damaged as well anyway.

I think that's asking a lot of her.

Doesn't she normally sing live with pre-recorded backup vocals?

Beyonce usually only sings the verses of her songs and the ad libs + bridge. Unless it's a ballad in which case she sings the whole thing. That could work for Britney. Her songs aren't as demanding anyway.

I don't know how many shows this is about, but if it's for an entire year (or longer) they can hardly expect her to sing live every night.

Uh-oh
