I just found this video on YouTube that was recently uploaded (I believe by former Monkees backing band keyboard player Dave Alexander) that shows The Monkees rehearsing "You and I" at Wembley Arena in 1997 during the Justus tour. The audio appears out of sync, but it's definitely interesting footage and something I haven't seen previously.
