Circulate was the second solo album of Neil Sedaka after his 1959 debut solo album Rock with Sedaka. Circulate was released in 1961 on RCA and was produced by Al Nevins and Don Kirshner. Except for the title song "Circulate" and "I Found My World In You", the whole album contains covers of the 1930s, 1940s and 1950s songs as interpreted by Sedaka. Two of the songs were re-issued as B-sides of other hits: "I Found My World In You" was the B-side of "Sweet Little You" later in 1961, and "Circulate" was the B-side of "Alice In Wonderland" in 1963. Sedaka later recorded Italian-language versions of "Smile" (as "Sorridi") and "All the Way" (as "Si' Amore")
