It's only taken 46 years, but an ongoing debate about one of Bruce Springsteen's best-known songs has finally been settled.

Originally released on 1975's 'Born to Run' album, the song 'Thunder Road' has divided fans for decades: some think that The Boss sings "Mary’s dress sways", while others are certain that it's "Mary's dress waves."

Now, an answer has finally been obtained - although not from Springsteen himself.

New Yorker writer David Remnick asked his long-time manager Jon Landau what the correct phrasing was, and he replied: "The word is ‘sways. That’s the way he wrote it in his original notebooks, that’s the way he sang it on Born To Run in 1975, that’s the way he has always sung it at thousands of shows, and that’s the way he sings it right now on Broadway.”

Considering how both phrases have featured in official Springsteen memorabilia over the years, it's no surprise that there has been confusion - but there you have it. It's 'Mary's dress sways'.
