From the inception of the Monkees multimedia project, Michael Nesmith was rightfully insistent that his compositions not only be considered for use on their recordings, but that he should likewise be the producer. "Mary, Mary" was an early Nesmith effort and, prior to its inclusion on 1967's More of the Monkees, the Chicago-based Paul Butterfield Blues Band released a version on their classic East-West album in 1966. While the subject matter was typical of the boy/girl paradigm prominent in many bubblegum pop songs of the era, "Mary, Mary" chugs along to a propulsive R&B backbeat, driving the number with an infectious rhythm from tip to tail. Although Nesmith was a competent guitarist, the trademark opening lick is credited to Glen Campbell, then a West Coast studio stalwart. Campbell is instrumentally flanked by guitarists James Burton and Al Casey, keyboardist Larry Knechtel, drummer Hal Blaine, and percussionists Jim Gordon and Gary Coleman. Other Monkees involved in the making of "Mary, Mary" were Peter Tork (by all accounts the most skilled and studied musician of the four) on guitar as well as Micky Dolenz, who turns in one of his best lead vocal performances to date. While not issued on a single, the track was incorporated into five episodes of the Monkees' weekly prime-time sitcom: "I've Got a Little Song Here," "Find the Monkees (The Audition)," "The Prince & the Paupers," "Alias Micky Dolenz," and fragments of a performance from the first season finale, "The Monkees on Tour." Parties interested in hearing the Prefab Four play the cut live should seek out Summer 1967: The Complete U.S. Concert Recordings box set from 2001. Nearly two decades later, Run-D.M.C. scored one of their biggest crossover hits with a rap remake on the 1988 crossover smash Tougher Than Leather.
