By the time he reached his commercial peak with Imperial Records in the middle of the decade, he was specializing in pop ballads. His biggest success was the Top 10 Billboard Hot 100 hit "Hold Me, Thrill Me, Kiss Me," which reached Number 8 in 1965. It sold over one million copies, and was awarded a gold disc. He had a couple of other Top 40 entries over the next year, "Band of Gold" and "All of a Sudden My Heart Sings", as well as a few other easy listening sellers.
