Just an FYI... both Florence LaRue and the 5th Dimension (visit www.florencelarue.com) and Marilyn and Billy (visit facebook.com/McCooDavis) are still performing.
You could call it "Billy Davis JR and the 4th dimension"....billy was dominating the songs on their last albums. Not a very good move, since Marilyns hits were what kept the group going for a long time.
