right before the end-of-the-show onstage goodbyes, a loud altercation broke out backstage between chase and relatively new cast member bill murray. after several insults were exchanged (including chase's referencing murray's acne-scarred skin and murray calling chase a "medium talent"), the two actors began physically attacking each other. although by most accounts the fight had been at least partially instigated by john belushi, he was the one (along with dan aykroyd) who broke up murray and chase only moments before the entire cast regrouped in front of the live cameras. chase would host the show several times throughout the show's history, though he was unpopular with the cast and crew.
