First recorded by Johnny Winter (1970).
Hit version by Rick Derringer, writer (US #23 1974).
From the wiki: “‘Rock and Roll, Hoochie Koo’ is a rock song written by Rick Derringer. It was first recorded by Johnny Winter, with Derringer and other former members of The McCoys (‘Hang On Sloopy‘), in 1970.
“In 1973, Derringer recorded a solo version for his solo debut album All American Boy, and it became his only Top 40 chart hit. According to Derringer, ‘The first song I wrote for Johnny was ‘Rock and Roll, Hoochie Koo’. ‘Rock and Roll’ to satisfy the rock ‘n’ roll that I was supposed to be bringing into the picture, and ‘Hoochie Koo’ to satisfy the king of blues sensibility that Johnny was supposed to maintain. And it worked out great.’
“‘Rock and Roll, Hoochie Koo’ has since become a staple of 1970s rock music compilations and Classic Rock radio.”
