One of my favourite experiences of several was when I owned a small acoustic instrument and repair business in London. A small and attractive young lady walked in one day, picked up a guitar and started playing some very tasteful and distinctive slide guitar at which point I spontaneously said "Be Jaze, you're Jo-Ann Kelly aren't you!" (I had never met her before). We ended up having a great chat and jam and she was a regular visitor in the shop after that.
I was terribly saddened by her illness and subsequent passing away a few years later and felt terribly both for the passing of a GREAT talent and her family.
