He would be the interpreter who became an international sensation after he duped his way into signing at Nelson Mandela’s funeral.

I’m not sure if sign language interpreter Amber Galloway Gallego will achieve the same levels of fame (or infamy) here in South Africa, but her efforts at a recent Twista concert are still mightily impressive.

You have to love her enthusiasm, although the sound quality below does leave a lot to be desired:
