was dylan in any way affected by paul robison? >> he would have had to have been. paul robison was right in the middle of that world that i describe so, sure, he would have listened to it. and if you listen to "the lonesome road," you know, look up, look up, seek your maker before gabriel blows his horn, paul robison's version of that is, you know, the standard. so i'm sure. he hasn't written about it anywhere, but you could not have come of age when dylan did in that part of the world without being aware of paul robison and his music. folks, thank you very much.
