So Don Black, David Zippel and Richard Stilgoe were light-weights that ALW could roll over? Even as producer he would be expected to rehaul their material?
Good luck trying that one.
And in the point about less melodies in his later shows? That is only partly true because most of his later works have been book musicals with dialogue and are not entirely sung through. And for the record, SUNSET has at least 15 melodies, not 9.
