I have posted three audio clips from the 1969 concert bootleg tape on the Live Almanac's YouTube Channel. Don't get excited, though, and think this is the long lost holy grail of Monkees recordings. If you haven't heard this tape before, the quality is worse than horrible. You can make out some of the music (along with the hiss, buzzing and dropouts). The tape is the only one from the '69 tour that has surfaced, and it has been floating around the trade circles for years.
I decided to post the clips for the curiosity of it all. The audio is believed to have been recorded in Wichita, Kansas on May 10, 1969 at the Century II Convention Center. There are some better recordings of The Monkees performing with Sam & The Goodtimers (but not many), and they can be found on the 1969 tour page. (You can also hear a rare radio station promo appearance there that features The Monkees promoting the Wichita show.)
