Dedicated To The One I Love

In 1967, a subsequent and slightly more popular cover version by the Mamas & the Papas released on the Dunhill label went to number 2 on the Billboard Hot 100, kept from number 1 by "Happy Together" by The Turtles.
This version also reached number 2 on the UK's Record Retailer chart.

The lead singer on the Mamas & the Papas version was Michelle Phillips. It was the first time that Phillips was given the lead over Cass Elliot. The song was also included on the group's 1967 album The Mamas & The Papas Deliver.

While the song mixes of the group's singles differ significantly from their album counterparts with some frequency ("Words of Love" and "Creeque Alley," in particular, feature overdubbed instruments that don't appear on the album versions of the songs), "Dedicated To The One I Love" used the same mix for both single and album. However, there are differing versions of the song available.

The mono single and mono album versions are identical. In them, Michelle's voice is double-tracked, but mixed down into the 'sound' of one voice. Cass's vocals are more prominent on these, as is the piano accompaniment. The cold ending features all four group members in signature harmony.

The stereo album mix moves the piano to the back of the mix, and Mama Cass' voice is further blended into the others'. This is particularly prevalent at the end of the song, where Cass is all but absent.
Cash Box called the single a "groovey, harmonic, soft rock venture that is sure to please all of the group’s many fans."

The group appeared on The Ed Sullivan Show in 1967 to perform both this song and the single to follow, "Creeque Alley". Although the single has a running time of 2:56, and the group performed the song in its entirety, edited versions of the song appear on internet video sites with a much shorter running time.
