Does anyone know when Blondie's first appearance onstage with the band was? In the "Beach Boys In Concert" book, it states that Ricky started performing with them in September 1971. Did Blondie play any shows before becoming an official members in early '72?
"New York State University, State University Plaza, Albany, NY, March 16, 1972."
Both Blondie and Ricky.
