While “Wild Thing” remains his most iconic composition, his catalog extended far beyond a single hit. He wrote “Angel of the Morning,” a song that gained widespread recognition through Merrilee Rush’s recording, and his work was interpreted by artists such as Willie Nelson, Evie Sands, and Linda Ronstadt. His influence reached even further, with songwriting credits tied to performers including Janis Joplin, Cliff Richard, and The Hollies.
