The Monkees were a trio for a year or so (following the departure of Peter Tork who left voluntarily, citing "exhaustion").
They released two albums during this time - Instant Replay and The Monkees Present, but they also seemed especially interested in re-establishing themselves as a musical-comedy act with TV appearances on Laugh-In, Hollywood Squares, and this one - from a 1969 episode of The Johnny Cash Show.
Here, the boys perform "Nine Times Blue" - an excellent Mike Nesmith song that never managed to find its way onto an original album. (It's all over the CD's now - as various bonus tracks). Then, they join Johnny for an improvised novelty song called "Everybody Loves a Nut".
Enjoy!
