UPDATE #1: Micky's appearance included discussions about the 2013 Monkees tour, the Headquarters and Head albums, The Monkees' confrontation with Don Kirshner at the Beverly Hills Hotel in 1967, as well as Micky's recollections about his attendance at a Beatles recording session for "Good Morning Good Morning," which ultimately appeared on Sgt. Pepper's Lonely Hearts Club Band. (Micky's version of the song was played at this point.) His Beatles song request was "Oh Darling" from Abbey Road, a favorite of Micky's and one that is often on the setlist at his solo shows.
UPDATE #2: Here's video of the event. Check out Gary Strobl in the studio holding a camera and filming Micky's appearance. (The video below does work despite looking like it's empty!)
