Watch the From Tiny To Junior online guitar lesson by David Blacker from Swing Blues Survival Guide: Lead
This piece originated from a Junior Watson solo that I came across in a YouTube video. However, I found out later that the 2nd half of the solo was quoting a number of lines from a Tiny Grimes solo in a song called "Call of the Wild" off his recordings with The Rocking Highlanders, ergo the name "From Tiny to Junior". It's got a lot of great west coast/jump language in it. I recommend taking it slow or learning it at half tempo as it's got a lot happening.
