The success and popularity of Bob Dylan’s Theme Time Radio Hour hasn’t gone unnoticed. Sirius XM Radio has now announced the expansion of the program to allow for longer, uninterrupted playtimes.

Dylan’s show will now run for four consecutive hours of the musician’s acclaimed blend of traditional-style hosting and hand-selected tracks.

The program will remain in its regular time slot and channel on Wednesdays at 11am EST on Deep Tracks (Sirius channel 16, XM channel 40) with the longer running time.

Theme Time Radio Hour’s new format begins on Sunday, February 8th 2009 with an encore of Wednesday’s episode at 4pm EST and will air on The Spectrum (Sirius channel 18, XM channel 45).
