 Tracks such as the album version of "Run Away Child, Running Wild" from "Cloud Nine", "Take a Stroll Thru Your Mind" from "Psychedelic Shack", and "Smiling Faces Sometimes" from "Sky's the Limit", all run at least eight minutes.At Whitfield's insistence, a large portion of the additional running time for each song consisted of instrumental passages without vocals.For example, the hit version of their smash 1972 single "Papa Was a Rollin' Stone" was nearly seven minutes, featuring an instrumental intro that was almost two minutes, a rarity for songs of that era.
