A few years ago, a deal was struck with the authorities whereby Christiania's residents would buy the land for $12.5m (£8.75m) – way below market value. The deal was supported by a loan from those very authorities – with no set payback date. The idea was to sell shares to residents. They didn't seem that interested, as might be expected of the anarchically inclined. Little more than $1m has been raised.
Traditionally, a pop star would celebrate newfound success by buying their mum a house. When “7 Days” has made its millions , perhaps Lukas Graham could go one better and buy his mother shares in her whole home town.
