Max Rebo of course!
These guys could jam in a way no other Star Wars band could. If they were good enough to play Jabba the Hutt’s lair, they’re good enough for a musician biography pic.
I could just see them hitting all the musician bio-pic notes.
Max Rebo, an Ortalan tried and true, grows up poor in Springberry, Orta, the Ortalan home planet.
During a deadly bobbing-for-songbird incident, Max Rebo accidentally drowns his more talented younger brother.
As a result, Max Rebo goes blind. But get this, his blindness allows him to hear the notes of the Ortalan keyboard in a way no player has before.
Max earns a living playing religious music in the temples of Ortalan worship, which are scandalized when he uses the tempos, melodies, and rhythms for a more popular, interplanetary style of music.
He is ostracized, but records a hit song.
Young and hungry, he has the world at his feet. He goes through a destructive, ego-driven moment of sex, drugs, and rock and roll.
And then he is redeemed by a beautiful woman. Her name is Sly Snootles, a Pa’lowick beauty with a song as soft as satin, legs that go all the way up, and a snout that rivals a trumpet.
At long last he writes his most definitive song, and dies fulfilled, having reached a far greater depth of spirituality, complexity, and understanding of the alien condition. He is a wise, old man.
Light years (and a galaxy) far, far away from the young pop star he once was.
