One of the highlights of the early Pebbles volumes was Phil the Frantics' "I Must Run," an obscure single which captured the early Zombies' sound with uncanny accuracy. The close resemblance, in fact, was no coincidence: so much of the melody and arrangement was lifted from the obscure Zombies' B-side "I Must Move" that the Frantics would have surely lost a plagiarism suit. The Phoenix-based band began as a much more frat-rock based act, adapting to the British Invasion sound after 1964. They recorded a few singles in the mid-'60s and scored a few local hits, "I Must Run" (which was produced by Waylon Jennings) being the biggest. Nothing else they recorded, however, was as memorable as that one Zombies ripoff. ~ Richie Unterberger, Rovi
