Damn Right I've Got The Blues
The book "Dam Right I've Got The Blues / Buddy Guy and the Blues Roots of Rock-and-Roll written by Donald E. Wilcock with Buddy Guy mentioned Johnny Winter on page 87, 113 & 132.
Page 87:
Dick Waterman had plugged Buddy into the "underground rock" scene
that had sprung up and had become as popular as the British blues-rock in the
form of the Grateful Dead, Jefferson Airplane, the Steve Miller Band, the Blues
Project, Johnny Winter and Janis
Joplin.
Page 113:
In 1984, Alligator released its first Johnny Winter album, Guitar Slinger.
It broke convention for the label, because Winter was better known as a rock
guitarist than for his Texas-based blues roots. It became Alligator's first
top-200 record on the Billboard magazine charts, fueling Bruce Iglauer's
ambitions: He want to record Buddy
Guy. Buddy was nervous about maintaining the artistic control he'd had
on Stone Crazy, and Marty assured him that a major label deal couldn't be
far off.

The first thing Virgin asked was what material Buddy would be recording. The
label had signed Albert Collins and Johnny Winter, and was looking for
a whole roster of blues artists.
