Here is one of my all time favorite performances by Martha Reeves. It's from the 80's, 1987 I believe because that is when I bought the original video. Martha starts out with "Heatwave" and concludes with "I'm Ready For Love". She is really working out. Martha, Mary Wilson and Valerie Simpson always seem to really be giving it their all when onstage and my favorite Motown ladies.

Also, I notice that Martha can change the tone of her voice at will in this clip. If you look closely you can spot celebrities like Carly Simon and Keith Hernandez in the audience. Check it out:
