The one confirmed live appearance by The Monkees in 1970 occurred at a festival-like event sponsored by WFIL Radio in Philadelphia, Pennsylvania. The show was held in May of that year. Monkees historian Andrew Sandoval, in an email to me in 2012, said that this show did indeed take place, and now we apparently have photographic proof! A big thanks to Sean Schafron for tracking down these pictures!!
