To survive, animals need somewhere to live, a place that provides the necessities of life, shelter from the elements and a refuge from enemies. Good homes are rare and competition can be intense – finding a home is one thing, but defending it is quite another.

'Every show is different. When the lights go down that's 30,000 people's lives colliding... for that one moment. Everyone that's there working or watching is there for that moment. It's when you're all kind of in agreement about what you're all doing at that time... so it's a wonderful feeling of togetherness and possibility Then I start getting real adrenaline... and start doing 'Rocky' shadow boxing and all that kind of stuff.
So I get as excited as anyone else. And I still get that excitement when I go and see anyone else's concert. I love that moment. And then it's about trying to hold that energy for an hour and a half... because it can go if you're not careful Whilst it might not be perceived as cool to be really enthused by the fact that people show up to hear your music... we don't really give a f***, we really love that and it's exciting, you know?'

The Dutch Golden Age saw map-making reach a fever pitch of creative and commercial ambition. This was the era of the first ever Atlases - elaborate, lavish and beautiful. This was the great age of discovery and marked an unprecedented opportunity for mapmakers who sought to record and categorise the newly acquired knowledge of the world. Rising above the many mapmakers in this period was Gerard Mercator, inventor of the Mercator projection, who changed mapmaking forever when he published his collection of world maps in 1598 and coined the term 'Atlas'. The programme looks at some of the largest and most elaborate maps ever produced, from the vast maps on the floor of the Royal Palace in Amsterdam, to the 24 volume atlas covering just the Netherlands, to the largest Atlas in the world, The Klencke Atlas. It was made for Charles II to mark his restoration in 1660. But whilst being one of the British Libraries most important items, it is also one of its most fragile so hardly ever opened. This is a unique opportunity to see inside this enormous and lavish work, and see the world through the eyes of a King.
