Two fabulous tracks from way back when. First up, a masterclass in duetting - Billy Eckstine and Sarah Vaughan, Passing Strangers.
And another great Jazz singer, with one of her more popular, less Jazzy outings, but still a gorgeous track, Ella Fitzgerald, Ev'ry Time we Say Goodbye, complete with that fabulous line, 'but how strange the change from major to minor'
