re: this title; Even though I haven't seen it, I'm pretty sure it's way too early to have been made in 73.

Gordon as a teen co-director even before being launched as a stuntman at Shaws ca. 75? I think it's production date is closer to its theatrical release date if not later. Please verify.

...you guys did have it covered, a year ago. The proof is in the pudding, even if it is newer revised video calligraphy credits to give it away for me. No further comment since I don't have this one to claim anything to the contrary. Once again, a video release to cash in after newfound fame for a cast member. Grindhouse anyone?
