"Twelve Thirty" a.k.a. "Twelve-Thirty (Young Girls Are Coming to the Canyon)", is a song by The Mamas & the Papas. After the release of the group's third album—Deliver—and their appearance as the closing act of the Monterey International Pop Festival, the group was scheduled to appear in England. The visit was catastrophic for the group, resulting in Cass Elliot leaving the group temporarily. The group had completed four tracks for their fourth album—initially titled Springboard—but when the group fracture occurred, progress on the new album stopped completely.
