The last line from the lyrics you cited - "Look up, look up, seek your Maker, 'fore Gabriel blows his horn" - was lifted from an old song called "Lonesome Road". Sinatra recorded the definitive version on his 1957 "A Swingin' Affair" album. Louis Armstrong, Bing Crosby, Van Morrison & scores of others have also taken a stab at the tune.
Your point that Dylan isn't and never really was a man of the left bears repeating. Liberals so dearly want to claim him as one of their own that they're willing to ignore over forty years of music, lyrics and interviews that suggest otherwise.
I am not sure that Dylan was not, at one time, a lefty...he may well have been..he was, after all, buddies with Alan Ginsberg and Lenny Bruce...
I believe his faith may have changed his world view to a large extent...His songs reflect a pro-Israel viewpoint (The Neighborhood Bully), he laments dependence on foreign oil (Slow Train Coming)..and he decries pornography in the schools (When You Gonna Wake Up)...hardly the stuff of the ACLU and the People For The American Way..
Thanks for the note about the lifted line...
