LOS ANGELES — Three years before Bob Marley died of cancer at 36, the reggae legend charmed a lively crowd at Boston's Music Hall.

Close your eyes and picture it. The year is 1978, and a sweaty Marley and The Wailers are already 10 songs deep when he transitions into "War."

A fan standing in the front row filmed Marley performing the Rastafari anthem; the lyrics are borrowed from a speech Ethiopian Emperor Haile Selassie delivered to the United Nations in the '60s. That unreleased footage is debuting here on Mashable.

Marley's family released the intimate footage, which will appear on Easy Skanking in Boston '78, a compilation of once-private videos and live audio from June 8, 1978 — to celebrate what would have been Marley's 70th birthday.

The 46-minute video will feature seven of the 13 songs from that 1978 show:

"Rebel Music" "I Shot the Sheriff" "No Woman, No Cry" "Lively Up Yourself" "Jamming" "War/No More Trouble" "Exodus"
