Ozzy Osbourne’s career is coming to a close, but the legendary rock star still has one thing left on his bucket list. During an episode on his Sirius XM show Ozzy Speaks, the Black Sabbath frontman told co-host Billy Morrison he would like to do a duet with Paul McCartney.

The update comes just weeks before Ozzy is due to take the stage at Villa Park in Birmingham on July 5 for Back To The Beginning for his final live performance. The special homecoming show will feature a short solo set before he reunites with Black Sabbath bandmates Tony Iommi, Geezer Butler and Bill Ward for the first time in two decades.
