Cover Riddle #5

Like Batman, James Bond, and Alien before it, the Cover Riddle is resurrected. The last one I did was, oh, about 8 months ago. These aren't covers, but don't worry there will be cover answers.

Tell me the common thread that links these tunes. Bonus points for not using google, the bane of trivia quizzes everywhere (2nd only to wikipedia). I'm looking for the name of a film and perhaps how each track specifically relates.

Ralph Steadman - Little Boy Billee
Oasis and Friends - Fade Away
Shadowy Men on a Shadowy Planet - Hunter S. Thompson's Younger Brother

Piece 'o cake. Go.

(Actually I changed my mind, go ahead and use O Mighty Google. I changed one of the songs to make it slightly less obvious.)
