were giving out all this energy and nothing was coming back." His savior was the newly arrived twenty-one-year-old bookseller and Beat Generation devotee James Grauerholz, who worked for Burroughs part-time as a secretary as well as in a bookstore. Grauerholz suggested the idea of reading tours. Grauerholz had managed several rock bands in Kansas and took the lead in booking for Burroughs reading tours that would help support him throughout the next two decades. It raised his public profile, eventually aiding in his obtaining new publishing contracts. Through Grauerholz, Burroughs became a monthly columnist for the noted popular culture magazine Crawdaddy, for which he interviewed Led Zeppelin's Jimmy Page in 1975. Burroughs decided to relocate back to the United States permanently in 1976. He then began to associate with New York cultural players such as Andy Warhol, John Giorno, Lou Reed, Patti Smith, and Susan Sontag, frequently entertaining them at the Bunker; he also visited venues like CBGB to watch the likes of Patti Smith perform. Throughout early 1977, Burroughs collaborated with Southern and Dennis Hopper on a screen adaptation of Junky. It was reported in The New York Times that Burroughs himself would appear in the film. Financed by a reclusive acquaintance of Burroughs, the project lost traction after financial problems and creative disagreements between Hopper and Burroughs. In 1976 he appeared in Rosa von Praunheims New York documentary Underground & Emigrants. Organized by Columbia professor Sylvère Lotringer, Giorno, and Grauerholz, the Nova Convention was a multimedia retrospective of Burroughs' work held from November 30 to December 2, 1978, at various locations throughout New York. The event included readings from Southern, Ginsberg, Smith, and Frank Zappa (who filled in at the last minute for Keith Richards, then entangled in a legal problem), in addition to panel discussions with Timothy Leary and Robert Anton Wilson and concerts featuring The B-52's, Suicide, Philip Glass, and Debbie Harry and Chris Stein. In 1976, Burroughs was having dinner with his son, William S. "Billy" Burroughs Jr., and Allen Ginsberg in Boulder, Colorado, at Ginsberg's Buddhist poetry school (Jack Kerouac School of Disembodied Poetics) at Chogyam Trungpa's Naropa University when Billy began to vomit blood. Burroughs Sr. had not seen his son for over a year and was alarmed at his appearance when Billy arrived at Ginsberg's apartment. Although Billy had successfully published two short novels in the 1970s and was deemed by literary
