Sinatra and Hazlewood released the single "Some Velvet Morning" (U.S. No. 26), accompanied by a promo clip, in December 1967. The song is regarded as one of pop's more unusual singles; critic Cathi Unsworth wrote, "The puzzle of its lyrics and otherworldly beauty of its sound seemingly endless interpretations." The British broadsheet "The Daily Telegraph" placed "Some Velvet Morning" atop its 2003 list of the Top 50 Best Duets Ever ("Somethin' Stupid" ranked No. 27.) The song appeared on the duo's 1968 album "Nancy & Lee", about which National Public Radio commented in 2017, "... its sly, sultry movements both are a gem of traditional '60s pop and an inversion of traditional conceptions of romance."
