It is established that Bruce wrote RANDOLPH STREET about his grandfather, who was an electrician. Introducing "Factory" on 03 Sep 1978 in Saginaw, MI, Bruce told the crowd:
I was born on September 23rd 1949 in this little town called Freehold... my grandfather, me and my mother, my father. We all lived at my grandparents' in a house in town. [...] My grandfather he was an electrician and he used to fix second-hand radios. And I remember when I was five years old, before we were to leave, he used to take me with him outside of town in the summer, and they used to have mining workers, used to come off from the South and work in the fields outside of town. He used to sell them radios that he'd buy and fix, bring them out there in the trunk of the car and take me with him [...]
Everything makes me believe that the first house where Bruce and parents lived (located at 87 Randolph Street in Freehold, NJ) was his paternal grandparents', so it was his paternal grandfather, Frederick Springsteen, who was the electrician about whom Bruce wrote the song. However, in his new book The E Street Shuffle: The Glory Days of Bruce Springsteen & the E Street Band, Clinton Heylin wrote: "[...] he has already celebrated his grandfather, Mr Zerilli, in song [...] an autobiographical piece called 'Randolph Street'. [...]" This got me confused.
So, who was it, Frederick Springsteen or Thomas Zirilli?
And when did Bruce's grandfather (the electrician) pass away?
For the records, this is Bruce's family tree:
By the way, it's a beautiful song. Do give it a listen.
