The `Message In A Bottle` singer has "no idea" what he?ll do when he completes his present `Symphonicities` tour - where he is backed by Britain?s Royal Philharmonic Orchestra - but not having a plan helps him to be creative.

When asked if he finds having no agenda liberating or worrying, he answered: "Both. It makes me anxious of course. At the same time it`s a good place for creativity. It`s only out of anxiety that I ever produce anything worthwhile."

On plans to write new songs, Sting, 59, added: "I need the blank page and I need the panic. I`m not hungry to be adored or have approval. I don`t need that. I`m curious to see what I can produce at my age.It gets harder and at the same time it`s a wonderful challenge."

Sting has previously called the idea of touring with The Police - the band he rose to fame in, who played a lucrative series of comeback shows in 2007 and 2008 - "dreadful", but hasn`t completely ruled out the idea of touring with a rock band again, saying he will "If my instinct tells me."

For now, however, he is most comfortable playing with the orchestra.

He added: "I`m very relaxed in front of an orchestra, I don`t even sweat. I sing for three hours. I could do another three hours every night. And the musicians are playing with precision, passion and love."
