This documentary follows the Bee Gees – one of the most iconic bands of the disco era – through their rocky beginning, their rise to fame, and their enduring bond through music.

From early hits like 'To Love Somebody' to the well-known classics 'Stayin' Alive' and 'You Should Be Dancing,' the Bee Gees definitely made their mark on the music industry.

The Gibb brothers formed the band as children and wowed British record producers with their crisp harmonies and smooth style, which kicked off their multi-decade career.

Now, only Barry Gibb is alive to tell the story of how the Bee Gees became some of the best songwriters of their time.

In How Can You Mend a Broken Heart, American filmmaker Frank Marshall highlights the Gibb brothers' strong relationship and how their bond helped the Bee Gees create music that touched hearts around the world.
