Too bad Peter Fonda and Dennis Hopper never released their 3 1/2 hour original cut of Easy Rider. I guess what nowadays would be called the "Director's Cut", or the "Extended Edition". Peter Fonda showed this cut to his father, Henry, who liked it, and talked of releasing it after the theatrical version had played out. Back then, that would have meant a theatrical release, in the days before VHS cassettes and DVD's. On the music: CSN&Y's "Find The Cost of Freedom", performed acappella on their live album "Four Way Street" was originally written by Stephen Stills for the ending of the movie, but Fonda/Hopper instead used "Flow River Flow", written by Roger (nee Jim) McGuinn, and performed by the latest incarnation of The Byrds at the time (1969).
