There's an old story you've probably heard.

when i was a kid I wanted to play guitar, like Cliff and the Shads. But my Dad, who knew everything, so I thought.
Said, La! Real guitarists play with their fingers not a plectrum!
Nine year old Al said, who plays like that?
A bloke in Spain called Segovia.... and this black chap. he's american...called Josh White.
So eventually Josh appeared on English TV and my journey started.

When Josh was seven years old, he saw a blind man trying to cross the road. He helped him across. that man was Blind Lemon Jefferson and he asked the kids name.
I know a song about Joshua, said BLF, and played him Joshua fit the Battle of Jericho.
Its a song I'm now teaching to my little 7 year old uke strumming grand nephew, Joshua.
That in my book is tradition.
