At first glance, you might dismiss Journey Through the Past as just another sci-fi quickie. Please DON’T do that.

Songs include “Only Love Can Break Your Heart” and “Heart of Gold.” The direction of Journey Through the Past is credited to one “Bernard Shakey”-who also goes by the name of Neil Young ~ Hal Erickson, All Movie Guide
