Howlin Wolf

Hi, a friend and I swap CD's that we get each christmas and this year he lent (I have now ordered my own copy) me a copy of "Howlin Wolfs - Memphis Days CD?" We both really like it and agree some of our favorite tracks are; "Mr highwayman" and "California blues," and "How long how many more years."
If anyone else knows about this CD please let me know your thoughts, or just your general thoughts towards the legend that is Howlin Wolf!
