How does the phrase going electric pertain to Dylan?
appearing, unexpectedly, with an electric guitar.
When did this first occur?
Dylan had appeared at Newport in 1963 and 1964, but in 1965 met with cheering and booing and left the stage after three songs.
Why were people booing?
One version has it that the boos were from folk fans whom Dylan had alienated by appearing, unexpectedly, with an electric guitar.

Question: What is another version of the event?
