This is a very tricky song to figure out on guitar, according to Billy Gibbons of ZZ Top. Gibbons, who included it on his second solo album The Big Bad Blues
in 2018, told Songfacts
: "Bo's upside down/inside out guitar intro required many hours of figuring. When finally accomplished, there was much cause for celebration. You may think you know Bo but you've got to be severely analytical to really know, know, know Bo."
