Re: Cobus. Overrated?
As far as learning from unlikely sources there's a story about Keith Richards working for a long time to master a lick and never could get it.
Somehow fate had him talking to Bobby Goldsboro, the sappiest musician on the planet. Keith told him about this blues lick he couldn't figure out. Goldsboro said, hey I toured with them(him..whomever), let me show you. So, you never know.
(I probably butchered that story but I heard it second hand. I haven't read Life yet.)
