kerouac/shepherd, and garrison keiller
So now you know (through David Amram) that Kerouac listened to Jean Shepherd. They appreciated him because he was an improviser. Shepherd also had a great interest and connection to the current NY jazz scene in the 1950s, and played lots of jazz on his early radio shows. He was also emcee for several important jazz concerts in the late 50s.
Shepherd hated Garrison Keiller(so says two of my informants) because Keiller got the national attention Shepherd believed was due to HIM!
I wonder if anyone has a set of ON THE ROAD galleys to check on whether Kerouac mentions a radio talker.
