For their next two albums, "Every Good Boy Deserves Favour" (1971) – from which Hayward's "The Story in Your Eyes" was taken as a US charting single (No. 23) – and "Seventh Sojourn" (1972) (which reached No. 1 in the US), the band returned to their signature orchestral sound which, while difficult to reproduce in concert, had become their trademark. The title "Every Good Boy Deserves Favour" was borrowed, tongue-in-cheek, from a mnemonic used to remember the musical notes that form the lines of the treble clef: EGBDF. The opening track "Procession" was the only item composed by all five band members, a fascinating track depicting the "evolution" of music, leading into Hayward's "Story in Your Eyes". Thomas's reflective "Our Guessing Game" and whimsical "Nice To Be Here" offset the deeper drama of Hayward's "You Can Never Go Home", Lodge's "One More Time To Live" and Pinder's "My Song". Edge, the long-standing drummer-poet, started writing lyrics intended to be sung, rather than verses to be spoken – his "After You Came" (1971) featured each of the four lead singers taking a vocal section. Then in 1972, Lodge's songs "Isn't Life Strange?" (No. 13) and "I'm Just a Singer (In a Rock and Roll Band)" (No. 36) were lifted from "Seventh Sojourn" as charting UK singles. "Sojourn" also saw Pinder using the new Chamberlin instrument in place of the mellotron and Edge using an electronic drum kit. Pinder's stirring lament "Lost in a Lost World" opened this last "Core Seven" outing, while his sympathetic ode to Timothy Leary "When You're a Free Man", Thomas's romantic "For My Lady", and Hayward's serene "New Horizons" all stood out.
