James Brown and Pavarotti – “This Is A Man’s World”: One loves women and soul, the other food and opera – so what did they have in common? Well, apart from both being dead, one of the greatest ever duet performances after the duo hooked up at a concert in 2002 accompanied by a vast string section.

Meatloaf and Ted Nugent – "Free-For-All": He once screamed that he’d do anything for love – well, apart from that – and Meat Loaf definitely did not disappoint when he appeared next to the former Amboy Dukes guitarist, Ted Nugent, in his debut album Free-for-All in 1976.

Aerosmith vs. Run-DMC – “Walk This Way”: The rocking hip-hop classic helped to put rap on the map and push into the popular music mainstream. But this cult-classic is largely celebrated for its action-packed break dancing video starring Aerosmith’s Steve Tyler and Joe Perry.

Jay Z and Linkin Park – “Numb” / “Encore”: Not content with collaborating on just this one song, the King of Cool later went on to record an entire album with the heavy US rockers, titled Collision Course. Rumours are circulating that the 11 million album-selling rapper - who graces the cover of the new Esquire – is planning a reunion with the group at this years Isle of Wight Festival in June.
