As Simon Purcell wrote in "The Independent", "Whether he inspired or inflamed, Grigson's energies often acted as a catalyst and his interest in, and support for, young jazz musicians contributed significantly to the growth and consolidation of jazz education in Britain...Within the context of a leading international conservatoire, the Guildhall School of Music, in London, Grigson did much to demonstrate and explain the underlying principles common to jazz, classical and indeed all music, and as a result produced a generation of jazz educators possessing a thorough grounding in an area where much educational work is left to chance."  Among his published books are "Practical Jazz" (1988), "Jazz from Scratch" (1991) and "A Jazz Chord Book", as well as studies on the music of Charlie Parker, Louis Armstrong and Thelonious Monk.

By this time she had already filmed her scenes for the BBC's adaptation of "Wolf Hall" in which she played Jane Seymour, a role she had been offered whilst still studying at Guildhall.  There was some mild controversy following the initial airing of "Wolf Hall" after some historians's described Philips as 'too pretty' to play Henry VIII's third wife.  This criticism was disregarded by several critics who praised Philips' performance with "Screen Daily" naming her as a 'Star of Tomorrow'.  She went on to secure roles in "War & Peace", "Peaky Blinders" and "The Crown".
