Pharrell’s adviser is the legendary hip hop artist, Missy Elliott. The singers freaked out at the sight of her! Celeste Betton and Mark Hood sing “Ain’t No Mountain High Enough.” Amy Vachal and Jubal & Amanda face off with “To Love Somebody” by The Bee Gees. Ivonne Acero and Siahna Im perform “Keep Me Hanging On” by the Supremes. I’m not feeling these mouldy oldie song choices. Like AT ALL. Particularly for the younger contestants.
