Watch the Katy Did online guitar lesson by Corey Congilio from Blues Guitar Fakebook: Rhythm Vol. 1
Blues with a bridge! "Katy Did" uses the changes to "She Caught the Katy". The great thing about this tune is that it indeed has a bridge. I've worked the bridge into the chart as well as the track. This song is one of my all-time favs, and you can find several versions out there. Check it out!
