Version One, recorded in July 1966 and produced by Nez, showcased ace session players like James Burton, Glen Campbell, and Hal Blaine. Peter is also featured in the mix, playing guitar. This version was only heard on the TV show during the first season, and didn't see an official release until 1990's Missing Links, Volume 2.
The second version, from the group's third LP, Headquarters, features The Monkees on the backing track and was produced by Chip Douglas.
