Update: Pharrell Williams denies Imitating Marvin Gaye's Got it up

Pharrell Williams has denied copying Marvin Gaye's Got to Give It Up for the hit single Blurred Lines.

the producer and singer agreed he was "bringing out... that late-70s feeling" when he co-wrote the song.

Williams, Robin Thicke and rapper TI are being sued by Gaye's family over similarities between Gaye's 1977 song the 2013 hit Blurred Lines.

In court, Williams said Gaye's work was not on his mind when he wrote the song, but he later recognised a likeness.

"Sometimes when you look back on your past work, you see echoes of people."

"But that doesn't mean that's what you were doing," Williams testified in court in Los Angeles.
