A painting by a graffiti artist was among the official gifts to Barack Obama from David Cameron on his first trip to Washington as prime minister.

The work, Twenty First Century City, is by Ben Eine, said to be one of the PM's wife Samantha's favourite artists.

The 39-year-old artist recently sprayed the entire alphabet on shop shutters in a London street.

Mr Obama continued the art theme by presenting the Camerons with a signed lithograph by pop artist Ed Ruscha.

The piece, Column with Speed Lines, was chosen for its red, white and blue colours matching the British and American flags.

Not yet even for sending back the Churchill bust, but points scored by the Brits.

The cheerful little tune is "Lillibullero" an ancient Irish-English folk-tune that has been used as the station-ID by the BBC World Service (their international shortwave broadcasts) from World War II to the present. The pretty little song has been associated with rebels, warriors and commandos since it was first heard. There's a Wikipedia article about it.
