Ed mentioned not knowing Lotus Blossom at a jam session. How do you cats deal with a ballad you don't know and don't have a chart for, like at a jam session? I think uptempo tunes in 4 are easier to fake. But I think ballads, with the slow tempo and wide open spaces, are tough to fake, and even tougher if the melody is being embellished a lot. What are you all doin' in that situation?
