When Ryan Adams announced a batch of dates that will take his tour in support of Ashes & Fire into 2012, the HT fave singer-songwriter also added a December 5 appearance on The Late Show with David Letterman that will be followed by a full Live On Letterman set. Considering how hard it was (is) to get tickets to see Adams perform on this tour, the Live On Letterman webcast will offer fans a chance to see him free-of-charge. We’ll be on hand and will provide a full report following the show. If you want to attend, check out this contest from our friends at MyFreeConcert.com.
