In early November 1975, Ginsberg, Dylan, and Orlovsky visited Kerouac's grave at Edson Cemetery in Lowell, Massachusetts accompanied by a film crew who recorded the event. In this important letter, Ginsberg thanks Marshall Clements for supplying a map used by the crew and for his suggestions of texts for reading at the gravesite and chronicles the event: "we surveyed most sites - and today with Dylan went to [the] grave - He had film crew there - we stood by grave, talked - I pointed out Sam Sampas' stone - we read poems & lines out of Mex[ico] City Blues, then sat down w/ Peter [Orlovsky], Dylan played my harmonium & we improvised a blues, trading words, to Kerouac - then he took out guitar & I improvised a long celestial blues - Jack in the clouds looking down on us w/ a big tear - then we went to the Grotto [illegible] & Dylan talked to Statue of Christ, & lit votive candles & we babbled about God - & then light faded (after many beautiful film scenes shout around the Catholic orphanage & playground overlooking Merrimac) & we came here. Other film crew made many shots of mills & redbrick as per yr. selection from Maggie Cassidy & Tony Sampas' & mine from Dr. Sax, & mine from [Mexico City] Blues - Dylan said he'd read the Blues book, & [Doctor] Sax, & [Visions of] Cody, among others - long ago the Blues - Thanks again for sending yr selection of images - As ever, Allen." Ginsberg's return address on the flap of the mailing envelope reads "c/o Rolling Thunder". The Rolling Thunder Revue was Dylan's concert tour of fall 1975-spring 1976 featuring various musicians and players; Ginsberg performed with the group. In his capsule biography of Kerouac in Photographs (Altadena, CA: Twelvetrees Press, 1990) Ginsberg sees Kerouac "inspiring Bob Dylan to renovate U.S. folk lyric." Sean Wilentz, in a chapter of his Bob Dylan in America excerpted in The New Yorker on August 13, 2010 views Dylan's involvement with the writings of Kerouac, Ginsberg, Burroughs, and others as a key link between the folk music movement and the Beat generation. Folded for mailing, the letter, and its original mailing envelope, are in fine condition.
