They can do it like how Disney+ does on some films with stereotypes. Like the disclaimer they did for Dumbo.A simple warning couldn't suffice?
According to the description: "The audio comes from a Columbia House VHS, which sent to me by Larry T. and @C_A_P_. Some historical background - The film was originally released in 1943, and is a wartime tale about cat and mice. When it was re-issued, not only were the original opening credits cut, but a small line of dialogue ("We’re all glad to pay our taxes") during the opening number ("Ain't We Got Fun?") .
An interesting discovery there. Which Looney Tunes Columbia House VHS is that previously-lost dialogue from?
