Sharleen Spiteri presents her accomplished interpretation of the Billie Holiday classic God Bless the Child and Gwyneth Herbert reinterprets the Walter Donaldson and Gus Kahn classic Love Me or Leave Me with loops and beats. Jose James delivers a smooth and swinging version of Just Squeeze Me, a song made popular by Duke Ellington, while Krystle Warren performs a bluesy version of Cole Porter's risque Love for Sale and a string-laden performance of A Nightingale Sang in Berkeley Square.
