I guess it was Nathalie Cole who started the craze of duetting with dead partners (in her case her dad, Nat 'King' Cole). The result is usually godawful, and so is the case with Christmas Duets, a compilation featuring world renowned stars like Mel Torme, Supremes and Nina Simone singing together with an odd bunch of Dutch artists - jazzartists, popsingers and, er, Gerard Joling. Listen to snippets here, don't say I didn't warn you.
The sole track that's quite okay is the Wouter Hamel-Nina Simone duet.
