I was singing about six notes higher than I had to, in a range that kept me up in a bubblegum sound.

In 2003 Nancy Sinatra reunited with Hazlewood once more for the album Nancy & Lee 3. In December they released the "MOR"-psychedelic single "Some Velvet Morning" regarded as one of the more unusual singles in pop and the peak of Sinatra and Hazlewood’s vocal collaborations. Those close to the Sinatras claimed that family members were upset with the nude photo spread.

Sinatra also had a brief acting career in the mid-60s including a co-starring role with Elvis Presley in the movie Speedway and with Peter Fonda in The Wild Angels. The song was written by Lee Hazlewood who wrote and produced most of her hits and sang with her on several duets including the critical and cult favorite "Some Velvet Morning". Nancy Sinatra began her career as a singer and actress in the early 1960s but initially achieved success only in Europe and Japan.
