Which song did Nancy Sinatra sing in an episode of the American crime drama TV series "The Sopranos"?

Nancy Sandra Sinatra (born June 8, 1940) is an American singer, actress, film producer and author. She is the elder daughter of Frank Sinatra and Nancy Sinatra (née Barbato) and is known for her 1965 signature hit "These Boots Are Made for Walkin'". Sinatra began her career as a singer in November 1957 with an appearance on her father's television variety series "The Frank Sinatra Show" but initially achieved success only in Europe and Japan.

Sinatra appeared as herself on one of the final episodes ("Chasing It") of the American crime drama "The Sopranos". Her brother Frank Jr. had previously appeared in the 2000 episode "The Happy Wanderer". Sinatra sings "Bossman", a track off her 2004 album "Nancy Sinatra", to a gathering of the New York and New Jersey families celebrating Phil Leotardo becoming boss.

"Chasing It" is the 81st episode of the TV series "The Sopranos", the fourth episode of the second half of the show's sixth season, and the 16th episode of the season overall. The episode centers around Tony Soprano experiencing problems from multiple angles, from losing sports bets, owing Hesh Rabkin repayment on a loan, to intervening with Vito Spatafore Jr.'s behavior problems.
