Ring of Fire

Jewel wore dentures over her famously crooked teeth to play June Carter Cash.

In the Movie when June tells her son to bye to his Daddy, they noticed Johnny wasn't breathing & they call an ambulance.

2022, the surviving cast of "Emergency" state that Ambulance services wasn't readily available in the 1970's like they are today, mainly due to funding. June & Johnny was Married in the mid to late 1960s according to the movie.

If there was a town with an ambulance service, the service went through the coroner of the closest area in which you lived.

"Emergency" opened a lot of doors for people to be treated while on the way to the Hospital, but majority of the ambulances started rolling after Emergency left the air & went into syndication.
