What happened to the group from the 80's called TODAY?
They broke up and the lead singer became the singer Big Bub.
Both of those are correct spellings. Formally, it is 1980s but many people spell it as 80s because it is shorter and faster to write. We usually say 80s when we are talking about the previous 80s. For example, when it is 2190, we will call the 2180s the 80s and in the year 1490, they also called the 1480s the 80s. I hope this helps you.
