TLC performs medley on 'GMA' Fall Concert Series & The View...

It's very much understood that T-Boz has health issues and that they put a lot of focus into the dance portion of things. But would it seriously kill them to at least attempt to sing live once in a while? 

I love TLC like freshly baked cookies but I'm just not here for a poorly done lip-sync job. 

Check out T-Boz and Chilli performing a rather dancentric medley of their greatest hits 'What About Your Friends', 'Waterfalls' and 'No Scrubs' below.

They were also joined by Lil Mama, Keke Palmer, and Drew Sidora who all play the group in VH1′s 'CrazySexyCool: The TLC Story'.

 TLC's greatest hits compilation '20', which was released in stores today, is available now.
