chas ... unfortunately, I only got to see the last half or so ...great talent, great music ...

BTW ... I remember hearing in a recording of "Fingertips" that when Stevie started to take an encore solo, some band member was asking "What key, what key" ...
I found this on the I'net :

"The original bass player had already left the stage and Joe Swift, the bass player for the Marvelettes was already on stage, when Stevie started playing again. That's him saying "What key?". That's soul music for you! :)"

Great stuff ...
