Who called Bob "Judas"?

This question does not refer to the recently superannuated Premier of NSW's decision to accept a reported half million pieces of gold for doing some consultancy work, so the answer is not "most Australians with a well developed moral sense".

An Adelaide giveaway paper has offered a copy of the Bob Dylan No Direction Home soundtrack CD to the first four people who can identify the irate fan who shouted out "Judas" at a 1966 concert in the UK (when Dylan reverted to electric music). A Google search has narrowed the field down to two: John Cordwell and Keith Butler. See

I've neither the time nor the inclination to peruse the 21,100 or so links Google has thrown up and it's too late to claim a prize, but it would be interesting to know what the correct answer is.
