"Somebody Loan Me a Dime" by Fenton Robinson (Boz Scaggs also did a great version of this w/ Duane Allman on guitar)
"Fever" by Peggy Lee
"Hobo Blues" JL Hooker
"Early This Morning" Blind Blake (and it's cousin "Black Dog Blues")
"St. Louis Blues" great versions from Bessie Smith to John Fahey
"Two Legged Rat" Buddy Guy
"How Blue Can You Get" BB King ( breathtaking guitar intro)

PS Big Pink Lad, is that the Fleetwood Mac song that starts out "I'm crazy for my baby but my baby don't love me..."? Great song, I've been looking for a recording of it. vl
