I've always been a huge fan of Charlie, and my favorite tune of his has to be Christo Redemptor. Hell, it may very well be my favorite blues song, period. Saw someone posted him at the Hardly Strictly Bluegrass show. I caught him with Hot Tuna this past March when they came to Springfield. I love Jorma Kaukonen's guitar solo. Here's a recording from a show a couple months prior. (Quality isn't the greatest and the start of the song is missing, but still sounds great)
