This song will help you gain command and understanding of the famous 2-bar straight eigth groove known either as the "Hombone" or "Bo Diddley groove." Most often this groove is played as a one-chord blues. This piece is in the 12-bar form with a long V (five) and no urnaround is actually not a common blues form. The most important thing is to ge the groove going and get the band locked into the 12-bar form. You should not even start plaing until you can "mouth" out the groove. Record yourself doing it before you start learning the harp parts. You should also learn to give the band finger signals as to what the chord hanges are and be prepared t play the first chorus over again until the band is locked into the form and groove with you.
