Great song. You can find Mack's original on Lonnie Mack 'Strike Like Lightning' Alligator ALCD [1985]. The track has Stevie Ray Vaughan and Bill McIntosh helping out on National steel and slide respectively. Composer credits given a 'Mack/Wilkinson'.

'Next best thing to nooky, blues'. I took 'nooky' to have the same meaning as it does in Oz - 'sex'.
