The remembrance clip, set to the Bee Gees ballad 'Heart Like Mine', features never-before-seen home video footage of the Gibb brothers as kids, as well as career highlights and live performances, reported Daily Express.
The montage, which Barry posted on his YouTube page, is titled 'Bodding', Robin's nickname.
The singer lost his battle with cancer at the age of 62 on May 20 and Barry, the sole surviving member of the trio, has yet to make a public comment on his sibling's death.
Robin's twin Maurice died in 2003 of complications linked to a twisted intestine.
