"Now and Then" was followed up by the sort-of 50th anniversary of "Red and Blue".     This week we look at three albums of goodness from the folks at Universal Music.      The blue album is very much a compilation in the traditional sense -  a nice sampler for the Giles Martin post-2017 remixes.     This week we consider the additions to the collection, other choices that might have been made and what is that sound in "Hey Bulldog"
