Watch the I'm Worried online guitar lesson by Jeff McErlain from Blues Guitar Fakebook: Rhythm Vol. 2
"Worried Life Blues" was written and first recorded by Big Maceo Merriweather in 1941 and had since become a classic. The form is 8 bars. The song has been covered by many people, and is a staple of Clapton's live set. The version I'm playing here are the changes that Robben Ford put to it to jazz it up a bit.
