Automobile information was offered by David Burge as well as Joe Sheppard in the Daily Mail online, “Drive Me to the Moon! One of Five Vintage Italian Cars Given to Members of Frank Sinatra’s Rat Pack Emerges for Sale for £300,000,” August 13, 2017.

Description of the Tombs came from description of visitation from James Rhem et al., Plaintiffs, v. Benjamin J. Malcolm, Commissioner of Correction for the City of New York, et al., Defendants. No. 70 Civ. 3962. United States District Court, S. D. New York. January 7, 1974.

Information about the Daisy (yes, I know it was actually founded in 1962, after this book takes place) from martinostimemachine.blogspot.com. As a general note, I took liberties with events that occurred in 1961–1962. “Boys Night Out,” which members of the Rat Pack sing in December 1961 within these pages, wasn’t released by Sinatra until March 1962. I similarly played with the release dates of Lolita, the Jimmy Dean song “PT-109,” and so on.

Information about and attitude of John Wayne drawn from a 1974 BBC interview with him and from two UPI stories, “Sinatra Blasted for Writer Choice,” March 1960, and “Sinatra vs. ‘Big John,’” May 1960.

Dialogue from the Rat Pack show re-created in the book is largely drawn from a 1963 concert, Live at the Sands, with additional information from Mary Manning, “Rat Pack Reveled in Vegas; Revered by the World,” in Las Vegas Sun, May 15, 2008.

The relationship between Ambassador Kennedy and Gloria Swanson is detailed in The Fitzgeralds and the Kennedys: An American Saga, by Doris Kearns Goodwin. New York: St. Martin’s, 1991.

The January 1962 Los Angeles snowstorm was written about in “Freak Southland Storm Brings Snow, Sleet, Hail,” Los Angeles Times, January 22, 1962.
