Last night’s solo performances were, on average, average. Five of the 12 contestants singing last night will be voted off tonight – but not before getting the chance to sing duets with former American Idol contestants, including Kellie Pickler (sixth season contestant, seen here), Jordin Sparks, and David Cook. Unfortunately, last week’s duets, with the other 12 Idol singers still in this final year’s mix, were, on average, below average. To stay alive past tonight, this evening’s singers must sing with, not merely at, their duet partners.
