Here is a great video for learning blues songs... Warner Bro. Song Xpress Classic Blues Vol.3 Learn to play! Song covered... "BEFORE YOU ACCUSE ME,"
"LIE TO ME," "MARY HAD A LITTLE LAMB," "SPOONFUL." I've just learned
the first two songs. I would advise this for a beginner guitar player who can play open chords and barre chords easily. The songs are broke down and easily covered. Screen shots of hand and chords and tab are easily shown. I find these video help when I'm in a rut.
