Here is a rare find sent in to the Live Almanac by Lisa - an ad from 1970 for the only confirmed live appearance by The Monkees that year, playing in Philadelphia at a festival-like event sponsored by WFIL Radio in May 1970. I passed this along to Monkees historian Andrew Sandoval, and he told me that this show did indeed take place with Micky and Davy.
Little is known about any other concerts that might have been performed by The Monkees in 1970. Brendan Cahill, who with Monkees associate David Pearl managed the group throughout 1969, told Andrew Sandoval in 1991 that a short American club tour was conducted by Dolenz and Jones in 1970 to promote the Changes album. Andrew writes in the liner notes of the 1991 Listen to the Band box set that such a club tour took place. However, in an internet interview in 2006, Sandoval could not confirm this information as Cahill was deceased.
In his book, Andrew does write about a performance that occurred on November 21, 1970 at the Valley REC Center in Van Nuys, California with Micky, Davy, and Peter. The show was billed as "Freaky, Foxy, Funky Revival."
Outside of these two events, there are no other details about shows that Micky and Davy might have performed in 1970.
Thanks to Lisa for this great find, and to Andrew Sandoval for confirming everything. Below is the rare promo video for the only single from Changes, "Oh My My."
