RIP Neal Cassady and J. J. Johnson

Noted jazz trombonist J.J. Johnson died this date in 2001, the same date Neal Cassady died in 1968. I wondered about a Kerouac-Johnson connection and found this via Google Books from The Musical World of J.J. Johnson by Joshua Berrett and Louis G. Bourgois III (pp. 126-127). The passage is from Dan Wakefield's 1992 book, New York in the Fifties.
