Jason is just wild about a duet with Kim

Was it something Kim Wilde said that had Aussie star Jason Donovan in stitches?
Whatever the joke, he was happy to team up with the pop princess to support a good cause.
The dynamic duo proved a hit singing Harvest For The World. It was their party piece at a 30th birthday bash for human rights group Amnesty International – to be screened on ITV on December 28. They went down so well that fans hope they’ll duet again sometime.
