Williams explains album delay

Hip-hop star Pharrell Williams has defended the postponement of his debut solo effort, insisting the months of fine tuning will pay off.

The respected producer, who has previously collaborated with stars including Kelis, Justin Timberlake, Kanye West and Snoop Dogg, has been busy in the studio re-working the record and has replaced a few tracks, including a duet with jazz sensation Jamie Callum.
