London (ANI): Jay-Z performed a remix version of Amy Winehouse hit 'Rehab' at Norway's Hove Festival - a warm-up for his Glastonbury gig this weekend. The rapper remixed the Rehab track last year and the result would lend itself to a duet with Winehouse, reports the Sun. She plays Glastonbury's Pyramid Stage before him and a duet is possible - provided she has recovered enough after being diagnosed with emphysema.

His headline performance at Hove in Arendal also included reworkings of 'Umbrella', 'Smack My B***h Up' and 'American Boy.' During the middle of the set, a stage visual of George W. Bush morphed into presidential candidate Barack Obama, which prompted cheers from the crowd.
