Here is Fred Wesley's arrangement of the Herbie Hancock tune, "Watermelon Man." Being that it has become a blues and funk standard, soloing over this tune can be fun simply by using the blues scale, and that's exactly what Fred does with this solo. Learn the melody and some of Fred's patterns in all twelve keys.
Now, I don't really know what to make of this YouTube video, but it involves Herbie Hancock and Miles Davis, in 1991, performing "Watermelon Man." Take it for what it is.
