Has Prince played 21 shows (including the Troubadour and three House Of Blues performances) or is he supposed to play 21 nights altogether?

I realize that Sunday is his last show at The Forum. That said, has anyone kept tabs on the actual number of nights? Last I checked, after this Sunday's Forum show, I think he the tally has been 19 shows or something like that. Anyone keeping track?

Also, why was The Palladium projecting the Prince <--+O symbol on their wall the other night, if he was playing the House Of Blues? Could it be foreshadowing?

If it were strictly nights at the Forum, he'd have 6 left to do, starting after Sunday's show. I guess all those one-off club gigs counted or something. There goes my plans for a road trip.

Palladium and HOB are both LiveNation venues, more or less. They were just using the advertising space and probably having a little fun misleading people.

Here's a post from another thread:

GEORGE LOPEZ SHOW: April 13 = 1 show

FORUM: April 14, 21, 22, 23, 28, 29, 30 = 7 shows

FORUM: May 5, 6, 7 = 3 shows

TROUBADOR: May 11 = 2 shows

FORUM: May 13, 14 = 2 shows

HOUSE OF BLUES: May 25 = 3 shows

FORUM: May 27, 28, 29 = 3 shows

TOTAL: 21 shows

That's 21 shows in the LA area. Technically, it's only 18 nights, though. Then again, one Troubador show and one HOB show started at or after midnight. So if you want to get technical, it's 18 nights and 2 mornings.
