RUMSON, N.J. - Bruce Springsteen has a Halloween treat for his fans.

The rocker has posted a free download of a new song, "A Night With the Jersey Devil," on his website. The song has a blues beat, and Springsteen sings about "16 witches casting 16 spells."

Writes Springsteen: "If you grew up in central or south Jersey you grew up with the 'Jersey Devil.' Here's a little musical Halloween treat. Have fun!"

There's also a video showing Springsteen as the legendary Jersey Devil.

Earlier this week, Springsteen announced that he and his wife would not hold their annual elaborate Halloween display at their Rumson mansion. The couple said they were worried about people's safety because the event attracted too many visitors.
