I think though just to get in in depth, they should start by getting to know all of Rodgers&Hart, Kern, Arlen, the Gershwins, Porter, Berlin, Rodgsers&Hammerstein, Loesser, Lane, Bernstein, Adler&Ross before. Just not to miss a point of it

. And in GB of course the fabulous Noel Coward (Just listening to the cast album of "The Girl who came to supper")
