Anyway, one of the cofounders was musicologist Brian Currin. Brian has been running the official Rodriguez website (sugarman.org) I believe since the 90s. Together with Stephen Segerman, they found Rodriguez in Detroit and had him come to South Africa, where he was more popular than in his own country. The story goes that his daughter found the Sugarman forums and said, "I am Rodriguez's daughter." That started him touring.
In 2012 I got to see Rodriguez perform live at Grand West in Cape Town, South Africa.
Out of the crowd a lady adulated, "Rodriguez, we love you!"
Sixto answered, "I know that's the beer talkin', but I love ya' back." The crowd cheered.
Rodriguez then mused, "You wanna' know the secret ta'life?"
"Yes, Rodriguez! Tell us," the crowd bellowed.
"Breathe in. Breathe out."
And Rodriguez breathed out. Rest in peace, Rodriguez.
