A deep dive into one of the most successful pop groups of all time, The Bee Gees: How to Mend a Broken Heart presents the ups and downs, successes and tragedies, of a music family whose harmony in song masked a fractured collective off the stage.

There is a sadness in the opening minutes of The Bee Gees: How to Mend a Broken Heart that is hard to shake, as we watch singer and songwriter Barry Gibb reflect on being the last Bee Gee standing. The oldest of twin brothers Robin and Maurice, and the often forgotten Andy, a clearly guilt-ridden Barry openly ponders why he is the only sibling still alive. The answer to that is unknown. What is certain, however, is that the brothers Gibb established a legacy rarely rivalled in the history of pop music.

Director Frank Marshall (Alive) presents this legacy in a documentary that is as informative as it is entertaining. Featuring a long-list of interview heads (including archived interviews with those no longer with us), home video footage, and testimony from a smattering of famous faces (Eric Clapton, Noel Gallagher, Justin Timberlake, to name a few), …How to Mend a Broken Heart is a treat for fans and even those uninitiated with Barry Gibb’s sweet falsetto sounds.

Beginning with their first taste of success in Australia, to their breakthrough in Britain during the swinging ‘60s, to their trajectory into superstardom with the American led disco-era of the ‘70s, Marshall presents a pop-music phenom in the Bee Gees that relied on reinvention and adaptability to transition through swift pop-music phases that left many other bands collecting dust.

A trajectory of the Bees Gee’s greatest hits, ranging from the soul music inspired “To Love Somebody”, to the strut inducing “Staying Alive”, plays soundtrack and gives reminder of the infectious compositions these men gave to the world.

Of biggest remembrance is the brothers Gibb themselves, a music family who were either all for one, or none at all, with ego often tearing away at the camaraderie that, when at its best, flowed like the rich harmonies that elevated their songs. Barry Gibb has often lamented that he wanted his final moments with his brothers to be on better terms. His heart cannot be mended, but hopefully The Bee Gees: How to Men a Broken Heart will prove that the legacy of the Gibb brothers is unbreakable.
