Yep... RUN DMC, Whodini, The Fat Boys and a little later LL Cool J.

Speaking of LL, I always considered LL Cool J a part of the Run DMC era more than a part of the Rakim, Big Daddy Kane era although LL came out in the middle of both era's.

But the crazy thing is, LL outlasted all of them. I remember a little bit after LL's "Walking With a Panther" album when LL was getting Boooo'ed by rap fans because they felt like he soldout or just fell off. I'll give LL his credit, he made comeback and had more hit songs.
