Who says Simon Cowell’s an icy-veined grouch? The English impresario has announced plans to put together an all-star charity single to raise funds for the suffering people of Haiti. Details beyond that are scarce: According to a gossipy report in U.K. tabloid The Sun, Cowell protegées Susan Boyle and Leona Lewis have already signed on to the project, but those artists’ reps could not confirm this when contacted by the Music Mix. And it’s unclear what song they’d be singing.

So let the speculation begin: Which artists would you like to hear on a Cowell-orchestrated Haiti benefit single, and what would you have them sing? Suggest away in the comments, below.
