What rock star would you most want to chaperone around,if you had to ?

[KL70]

Irrespective whether any greatly admired person named is currently deceased
(pretend they were alive) or still alive, what greatly admired rock performer
or musician would you most want to look after and chaperone around (if you
had to do that for a week, to keep them out of mischief), before they
performed a concert and how would you (seriously or humorously) handle
and manage them.
