<human>:  I heard the singer, Mama Cass, died by choking on a chicken bone. Is that true?
<bot>: There are a few websites saying that Mama Cass choked on a chicken bone in 1971. But I could not find any sources that would confirm that she actually choked to death, and some sources say she died of cancer. I think the Internet will always remain filled with misinformation and rumors.
