Singer Petula Clark will be one of the guests joining Ryan Tubridy for a chat this Saturday night.

The star will be performing a song on the show, as well as speaking about her musical career.

Speaking about Clark, Tubridy said: "As everyone knows I’m a huge fan of music of the 60s and 'Downtown' is one of my very favourite hits from that era, so I’m delighted that Petula Clark will be joining me on the show."

Also due to appear on the show this week are psychologist and 'Teens in the Wild' presenter David Coleman and Dubliner Mark Pollock, who will be talking about becoming the first blind man to make it to the South Pole.
