there was no widely known or established myth or rumor about a "Bali break up" concerning Toto. It is possible that such a rumor or myth may have emerged or circulated in specific circles, but I cannot provide information on events or developments that occurred beyond that date.
To stay up-to-date with the latest news and rumors about Toto or any other band, I recommend checking reliable news sources or official statements from the band members themselves. Keep in mind that rumors can often be unsubstantiated and should be taken with a grain of caution until confirmed by credible sources.
