A backing track for Jeff Barry and Joey Levine's "Gotta Give It Time" was originally recorded in January 1967 and, 49 years later, it was finally given a vocal by Micky Dolenz (with backing vocals by Michael Nesmith) for The Monkees' 2016 album, Good Times! Andrew Sandoval discussed its original '67 attempt for an entry in his Day-By-Day book:
"...The studio musicians next settle in to recording Joey Levine's promising 'Gotta Give It Time,' not coincidentally co-written with today's session producer Jeff Barry. Only four takes are made of this garage-styled rock number, the final one being marked as the master. Had The Monkees ever completed the recording it could have been another '(I'm Not Your) Steppin' Stone.'"
Here's a homemade video for the song from YouTube, splicing "Gotta Give It Time" into the first season episode "The Chaperone":
