As Boozoo [Chavis] has pointed out, up until his introduction to [record producer Eddie] Shuler he normally performed unaccompanied….However to make Boozoo sound commercial, Shuler insisted on using a band [and] then enlisted Classie Ballou’s Tempo Kings.
"Classie had no idea what Boozoo was trying to do in the studio," said Shuler. "Things kept getting progressively worse. Finally I spent $1.25 on a half pint of Seagram’s 7 hoping the whiskey would loosen everybody up."
"After they finished the booze, though, things started sounding pretty good. Then I got them some more and everybody really started to cook."
Shuler recalls that on the original issue of “Paper In My Shoe,” Boozoo fell out of his chair near the song’s conclusion but kept on playing! To hide the noisy crash from listeners, Shuler faded the song’s ending, a production technique which hadn’t been used up until that time.
Album cover notes from The Lake Charles Atomic Bomb: Original Goldband Recordings (Rounder Records 2097), a collection and re-release of zydeco musician Boozoo Chavis’s recordings from the mid 1950s to the early ’60s.
So the practice of fading out pop songs toward the end of a track originated with a drunken recording session, apparently.
