Mary McCartney's documentary "If These Walls Could Sing" affords viewers with an unprecedented glimpse behind the gates of Abbey Road Studios. In a recent interview with me, McCartney provided insight into the documentary's genesis, as well as the musical magic that has been emanating from the studio across its remarkable 91-year history.
Pointedly, McCartney's film — streaming now on Disney+ — begins with early images of her parents Paul and Linda jamming with their band, Wings. When it comes to growing up with her famous father, Abbey Road has always connoted the notion of family for the documentarian, whose credits include "Mary McCartney Serves It Up," the hit cooking show in which she showcases vegetarian dishes in her London kitchen.
