Frank Sinatra, Jr. has played at times in
Las Vegas in the footsteps of his father, but this seemed to invite almost invariably negative comparisons. On seeing the act,
Forbes Magazine editor
Malcolm Forbes remarked, "Junior sure ain't Senior!," to which several readers wrote to ask if he would like his son
Steve Forbes to be referred to in this manner. Frank, Jr. appeared in the
Sammy Davis, Jr. television drama
A Man Called Adam in 1966 and hosted a summer replacement series while the popular
The Dean Martin Show was on hiatus in 1968. Since both Davis and Martin were close friends of Frank, Sr., it further fueled the notion that Frank, Jr.'s career was built on nepotism.
In the later stages of his father's performing career, Frank Sinatra, Jr. became his father's musical director and conductor.
In 1989, Sinatra did a cameo vocal on the acclaimed
Was (Not Was) album, "
What Up, Dog?" on Chrysalis Records, singing "Wedding Vows In Vegas" with the band. He also appeared with WNW doing that song on
Late Night With David Letterman on NBC the same year.
During the 1995/1996 television season, Sinatra was offered the role of
Vic Fontaine on
Star Trek: Deep Space Nine. Despite being a fan of the show and finding the role interesting, he turned it down, declaring that he only wanted to play an alien. (

He also had a guest spot playing himself on
The Sopranos, in a role where it was unclear if he was mocking or acknowledging all the stories about his father's involvement with the mob, and where he lets the character
Paulie Walnuts refer to him as the "Chairboy of the Board".
Sinatra appeared in a
2006 episode of
Family Guy, "
Brian Sings and Swings" (Season 4, Episode 19) where he was introduced as the "Member of The Board". He performs several tunes during the show, accompanied by
Stewie and
Brian. During the ending credits, he sings the Family Guy theme song. He also recorded a commentary for its DVD release.
