Who is the only father/daughter duet to top the US & UK charts?

Did you guess Frank Sinatra and his beautiful daughter Nancy?

In 1967, Frank Sinatra and his daughter Nancy were at No.1 on the UK and US singles chart with their hit 'Somethin' Stupid', making them the only father, daughter team to ever have a No.1 single.

The song was written by folk singer C. Carson Parks and originally recorded in 1966 by Parks and his wife Gaile Foote, as "Carson and Gaile".

A modern take on the song was also recorded in 2001 by Robbie Williams with Nicole Kidman, with that version also topping the UK charts.
