Bob Dylan has sparked rumors he's quit his three-year stint as the host of a satellite radio show - after naming the theme of his latest broadcast "goodbye". The folk singer has hosted the Theme Time Radio Hour (TTRH) program on Sirius XM since May 2006, playing a mix of blues, soul, country and pop music hits centered around a certain theme for each weekly show.

In between dishing out advice to callers, the singer made the cryptic musical theme clear during last week's 100th episode.

He ended the hour-long broadcast to Woody Guthrie's "So Long, It's Been Good to Know Yuh" and the sound of a needle screeching at the end of a vinyl record.

An announcement had yet to be made at press time.
