Jay-Z performed a remix version of Amy Winehouse single ’Rehab’ at Norway’s Hove Festival and this could announce a possible duet at this weekend’s Glastonbury festival.

Amy Winehouse is supposed to perform before Hov on Glastonbury’s Pyramid Stage but the english artist is currently recovering after being diagnosed with emphysema.

Jay-Z’s Norwegian performance also included reworkings of Rihanna’s ’Umbrella’, The Prodigy’s ’Smack My B***h Up’ and Estelle’s ’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.
