Madonna recently announced a career-spanning greatest hits tour.

An official press release announced that the upcoming concerts "will take us on Madonna's journey

through four decades of her career, paying lip service to the city of New York where she began her funnel

The tour will begin in July in Vancouver, Canada, with the options in New York, Barcelona, Paris

and Stockholm in addition to concluding in Amsterdam on 1 December.

Only one date has been announced for the UK so far, at London's O2 Arena on 14 October.

However, her calendar is vacant one week on either side of her earliest available date

suggesting more shows will be released when that date sells out.
