Bono 's band U2 won best original film song at the Golden Globes

The Federal Communications Commission rejected complaints from the Parents Television Council, who said Bono's use of a four-letter word was offensive.

The commission's enforcement bureau ruled on Monday that the singer's language was "fleeting and isolated".

U2 won best original film song for a track used in Gangs of New York at the ceremony in January.

The commission said offensive speech was language that depicted or described acts or body parts used in sexual or excretory acts. It also had to be measured against contemporary community standards.

Bono's language, it said, may have been "crude and offensive, but, in the context presented here, did not describe sexual or excretory organs or activities".

Art launch

It also ruled that Bono's use of the word was an exclamation or an expletive. It therefore did not breach US laws on broadcast indecency rules.

Meanwhile, the U2 singer was in London on Monday night launching a new CD version of Prokofiev's Peter and the Wolf, for which he has drawn illustrations.

The launch, at the auctioneer Christie's, was to raise money for hospices treating terminally ill patients. Huge prints of the artwork are to be sold for charity.

Bono said he began the project after the death of his father two years ago.

The music on the CD has been adapted by Irish singer-songwriter Gavin Friday.
