Bob Weir

@ericrhodes1 - I was at that 'Live Life Love' thing for Bill Graham at GG Park too. My favorite part was Bob and Jerry coming out with John Fogerty, who played Creedence songs for the first time in a very long time. 

@stuartk - the first 4 letters in 'weird' spell..... 

@larsman I remember that well. What a day that was! 

@stuartk Regarding Bobby's unusual approach, I just figure a C sharp is a C sharp no matter where you put it. More than anything, he made me want to listen more intensely.

Bobby was 16 when he met Jerry and formed what would become the Grateful Dead. For those of us who appreciated the adventurous musical trip he and the band took us along on, Bob was a bright light and a major part of our culture.

The only way to explain this is to delve into music theory and this doesn't seem the right place to do that.

What I can say is that is you were to listen to Weir's rhythm guitar in isolation, it might sound "off" to you, compared to somebody just strumming the basic chords.

In practice, how C# is perceived does actually change, depending upon where you put it, if we are talking about chords.
