[Verse 1]
[M]I walk a lonely road
The only one that I have ever known
Don't know where it goes
But it's home to me, and I walk alone[/M:It’s possible these lines were inspired by the chorus of Whitesnake’s ‘80s hit single “Here I Go Again”:]
[M]I walk this empty street
On the Boulevard of Broken Dreams[/M:The phrase “Boulevard of Broken Dreams” was first coined in a 1933 song recorded by many, from Bing Crosby to Amy Winehouse. It has since become a nickname for [Los Angeles' Sunset Boulevard](https://www.tripadvisor.com/Attraction_Review-g32655-d156501-Reviews-Sunset_Boulevard-Los_Angeles_California.html) – it passes through Hollywood, so many have seen their stardom dreams die in the street.
The title, “Boulevard of Broken Dreams”, is inspired by Gottfried Helnwein’s 1984 painting of the same name. This is a direct visual quotation of the painting “Nighthawks” by Edward Hopper that depicts a downtown diner at night. Helnwein replaced the diner’s occupants with American pop culture icons Humphrey Bogart, Marilyn Monroe, James Dean, and Elvis Presley to connect its bleak atmosphere with the tragic fate of some celebrities.]
