Billboard.com has the following information about stop number 2 on the One Nite Alone tour. Despite the date reference showing all recent results, I could only see this date available (the 6,871 figure indicates tickets sold number for the event):

Prince / Chicago Theatre / Chicago, Ill. / March 2-3, 2002
$577,195 (6,871 / 6,871) (2 / 2) $125, $85, $60
Jam Prods./Impact 3

Thats a tidy little sum for 2 concerts I'd say.

Good lawd....These shows are low key for Prince. Imagine what he would pull in if he played larger venues worldwide. Peace of Mind is a wonderful thing.
