Diesel is still mourning the loss of his good friend, who died in a car crash in late 2013, and in a video posted on his Facebook.com page on Thursday (21May15), he is using the power of music to honour Walker and his legacy.

Diesel wrote the caption, "The ever continuing process of healing... All love...," and in the clip, he begins by saying, "A little something for my brother Pablo."

The actor sings an emotional version of the song as a montage of photos and behind-the-scenes footage from the Fast & Furious filming days is projected on a screen behind him.

Diesel sings the powerful lyrics, "You're gone and I got to stay high all the time to keep you off my mind," and at the end, the words, "Missing you" flash across the screen.

Diesel previously covered Wiz Khalifa and Charlie Puth's hit song See You Again, a tribute track to Walker from the Furious 7 film.
