A friend of Mike's in the pre-Monkees era, John London later accompanied Mike to Los Angeles to try their hand at the music scene there. London later became Mike's stand-in on the television series and would occasionally play bass guitar on Monkees recordings. He later co-wrote "Don't Call on Me" with Mike, which appeared on the group's fourth album, Pisces, Aquarius, Capricorn and Jones Ltd. After The Monkees, Mike asked John to join him in the First National Band.
