well, Deadicated, i'd go for 1/11/78 first. a rather enveloping jam before slithering into St. Stephen, but Charlie Miller's admirable attempts on archive.org with 1/11/79, plus a penchant for Estimated/He's Gone/Drums suggests a healthy alternative.
bur after a slinky Gene Ammons and a soulful Sam Cooke, i guess '78 comes a' calling.
Gene Ammons "Funky" 1/11/57
Sam Cooke "Harlem Square" 1/11/63
Dead 1/11/78 or 1/11/79 Haven't decided yet. Whad'ya think?
