The Bang Bang hitmaker appeared on U.K. chat programme The One Show to talk about Frank Sinatra: The Man and His Music, a production featuring rare footage combined with the star's music and a dance troop, which is due to hit the London Palladium theatre in July (15).

Sinatra was overcome with emotion as she spoke about the show and how much she misses her father, who would have celebrated his 100th birthday this year (15).

She says, "I'm in tears right now... It's (talking about him is) hard to do because there's so much emotion involved... I want him to be here... It's (the show is) very technologically advanced so we're waiting with bated breath, we're sure it's going to be great. The orchestra is live, the voice of course is tracks and we don't know exactly what songs yet but hopefully they will be the favourites but we don't know, we're in the clearance process right now, so it takes time... We want people to feel as though they're experiencing a live concert even though Frank isn't with us anymore."

Sinatra died in 1998 at the age of 82.
