A big thanks to Bill Shinn for sharing an audience recording from the 1989 summer tour over at Iain Lee's Monkee Bootlegs Facebook page. Check out the '89 North American/Japanese tour page here on the site to listen to a radio advertisement for this show (which can be found at the bottom of that page).
Maybe Bill or someone can leave a comment letting us know if this was the first or second show at Humphrey's that day.
