Yeah Marciano Walcott II, The bout that follow was Billy Oakland Smith vs Billy Nobel light heavyweights.
Was that a "walk-out" bout? Rock-Walcott II was an early TV bout in the 50's.....maybe the producers were trying to plan for a quick KO by Marciano which did occur in one round.
Perhaps, I have Walcott Marciano II, PLUS the bout that follow. The annoucer even said 3 bouts to follow on the card during the intros of Marciano Walcott II. It was the feature attraction, but not the main "EVENT".
