Did I misunderstand it, or did his mother actually drop him off at Connie Stevens's house and then abandon him? If she really did that, he is a truly decent and forgiving person for later reconciling with her and fulfilling her last wish.
Apparently you never heard....this is a FABRICATION on the part of George Hickenlooper, voiced by Kim Fowley....I am IN the movie, I ought to know...
These fabrications (or "Hollywood-ized") things happen, unfortunately, too often...Luckily, this was about the only distortion in an otherwise truthful film...However, the director concentrated too much on sadness and weirdness; this film screams to be re-cut.
When Rodney gets his "Star" on the Walk of Fame, I'd love it if a financier bought up the rights to the film, and gave him unprecedented carte blanche to make an ARTIST'S cut of this underproduced masterpiece...
