Expose was a chart topping Miami based girl group that got caught up in a protracted legal battle involving labels, lawyers, songwriters and publishers. Eventually the original three members were replaced and the band continued, and you can find them at 'relive the 1980s' type concerts to this day.
But what happened to the original girls of Expose? I found one. Here's a YouTube of Laurie Miller doing a live performance in 2008. She doesn't allow embedding so you have to click here to see it.
Here is her personal website. See what she's been up to and what she's got coming up.
