Soul superstar Prince was determined to complete his 21-date London residency last summer (07), because people kept trying to talk him out of attempting 'the impossible'.
The Purple Rain singer sold out all gigs on the tour at the capital's O2 Arena - a feat that surprised even the star himself.
He says, "This was a landmark event. No one believed that it would do what it did. ...Everyone tried to talk me out of it.
"I couldn't have sold out 21 nights in London in the peak of my career; it would have been an impossibility."
And Prince hopes all artists will one day get the chance to do the same.
He adds, "I look forward to these years where everything is just open sky. I wish this for every artist: freedom."
