Canadian pop singer Nelly Furtado's Twitter admission that she performed for members of embattled Libyan leader Moammar Gadhafi's family puts her on a select but growing list of top-flight entertainers who have done so.
Pop stars generally xerox other acts' looks and hooks -- it's expedient, and it works. But Nelly Furtado's multiplatinum 2000 album, "Whoa, Nelly!" (which included the loosey-goosey soul-folk hit ''I'm Like a Bird''), felt like an original. The Canadian's debut was mass-market pop at its best: fluffy, giddy, uplifting, idiosyncratic.
