In October 2020, Sinatra and Light in the Attic Records announced plans to release the Nancy Sinatra Archival Series. The first release is to be a Record Store Day Black Friday exclusive 7" vinyl single featuring two Sinatra/Hazlewood duets, "Some Velvet Morning" and "Tired of Waiting for You." A new 23-track compilation, "Start Walkin' 1965–1976", will follow in February 2021. The first single, a remastered reissue of Nancy & Lee's 1976 Private Stock single "(L'été Indien) Indian Summer", was released as a digital exclusive on October 21, 2020. Some of Sinatra's past albums will be issued on CD for the first time, including her first record with Hazlewood, 1968's "Nancy & Lee", and its follow-up, 1972's "Nancy & Lee Again".
