Jay-Z to play another Obama gig

Jay-Z will play another free concert to rally support for US presidential candidate Barack Obama in the run-up to the election.

The 'Big Pimpin'' star has already backed Obama's White House campaign by playing a free gig in Detroit, Michigan earlier this month. A second date, scheduled for October 5 in Miami, Florida, had to be scrapped after the rapper suffered a throat illness.

But he is to give the Democrat's ticket one last push with a show in Cleveland next Wednesday.

The event will be hosted by basketball star LeBron James.
