"But now I wanted to take it a totally different way. So I said, 'Hey, this tune lends itself to be a total downhome blues," said Davis. "And that's the way be took it because it is a blues number."
They're now working on an expanded version of their "Blackbird" album...and their music is being noticed--even in "Billboard."
"We haven't been in "Billboard," you know, you're talking about years. It's been quite a few years," said McCoo.
"Since 1977!" said Davis. "It's been that long."
Billy and Marilyn first gained fame with The Fifth Dimension. The group got a star on the Hollywood Walk of Fame 20 years ago. And now, another one is on the way!
"Our second star on the Hollywood Walk of Fame. And this time, we're going to be the first African-American couple to get a star together," said McCoo. "And we're just really excited about that."
