When did meatloaf have his heart attack?

This is a bit of a trick question! Meatloaf, the rock star, is a person, and people have heart attacks. "Meatloaf" the food, is not a person and therefore cannot have a heart attack.

It seems you are trying to make a joke! 😊 Perhaps you were thinking about the song "Paradise by the Dashboard Light," which Meatloaf is famous for, and the line about the "heart attack in a fast food nation"?
