 He also helped sing on back up and arrange the music to "Not Fade Away" (which he helped write), "I'm Gonna Love You Too", "That'll Be the Day" and "Maybe Baby".It was around this period that he also wrote and produced the single "Look to the Future," which was recorded by Gary Tollett and the Picks, who often did back-up vocals for the Crickets.Since he had a slight resemblance to Holly in his skinny posture and spectacles, he was often called "the other guy in glasses" by critics in their reviews.
