This from-the-stage shot of Friday's show from Last Night’s Party (NSFW) shows that Rose uses (or at least has access to) a TELEPROMPTER.

At least they didn’t spell out “na-na-na-na-na-na-na-na-knees, knees.”
In one of their old videos...maybe Live and Let Die? He had a teleprompter
as well. I grew up thinking "the monitors" were teleprompters, till one day
my dad had to set me straight. Thanks Axl.
When Lisa Marie Pressley sang at the NBA finals a few years ago, I prompted
her lyrics so that she could LIP SYNCH! Since she was on the floor of a
basketball stadium, at least a third of the audience would have been able
to see the prompter.
