Bob Dylan has posted an unreleased song called Murder Most Foul, which deals with the assassination of JFK, and issued a rare public statement in which he thanks fans for their support and loyalty.

The near 17-minute ballad is Dylan’s first new song in eight years and looks back on the killing of President Kennedy on "that dark day in Dallas."

In typical Dylan fashion, the song also references various cultural figures and events of the era, including The Beatles’ early US hit I Want to Hold Your Hand, Woodstock, Patsy Cline, and, later, The Eagles. 

Writing on Instagram, the 78-year-old music veteran says, "Greetings to my fans and followers with gratitude for your support and loyalty across the years.

"This is an unreleased song we recorded a while back that you might find interesting."

in what appears to be a reference to the current Covid-19 outbreak, he adds, "Stay safe, stay observant and may God be with you."
