Joanna Lumley and Jennifer Saunders talk about Ab Fab, Rebel Wilson says she begged for a part in the new movie, while Iggy Pop and Josh Homme perform live in the studio.

Jennifer Saunders, talking about Absolutely Fabulous: The Movie and how it came about 26 years after the original series, says, "People asked me all the time and finally I thought it was a good idea to make it. I procrastinated for a long time - though I like to call it 'thinking time.'"

Talking about Kate Moss, and asked if she had another super model lined up in case Kate wasn't available, Jennifer says, "The funny thing was I had sold the idea of the movie to the studio and the BBC and then realised I hadn't actually asked Kate. Luckily she said yes and was really cool about it."

Asked about the very first series of Absolutely Fabulous, Joanna Lumley reveals she and Jennifer didn't hit it off immediately, "It was very awkward at the read through. It was just the two of us and she just stared at me. I told my agent I didn't want to do it and she said, 'It's just a pilot, just do it...'" Jennifer interjects, "Joanna just wasn't what I had in mind for Patsy. I saw her a low-life journalist. But Joanna brought so much more to the role and we had fun inventing the character."

Joanna, asked if her family have seen the movie, says, "It's the first Ab Fab that my grandchildren are old enough to see. Quite rightly they haven't been allowed to watch it before now. They were silent for a long time after watching it but they love it now!"

Revealing she was nervous about snogging Leonardo DiCaprio in The Wolf of Wall Street, Joanna says, "We went for it but there was a lot of peppermint involved as we were both quite anxious about it. We were both very clean, like a surgery." Adding, "He was very charming."

Rebel Wilson, talking about her cameo role in the Ab Fab movie, says: "I was living with Matt Lucas at the time and told him I had to be in the film so I wrote a begging letter to Jennifer. I had hoped to be Patsy's long lost child - the one she forgot she'd had!"

Asked about taking the lead in Guys and Dolls in the West End, Rebel jokes, "It starts next week and I am not prepared," before singing one of her major numbers.

Iggy Pop and Josh Homme join Graham for chat before performing Sunday live in the studio. Asked about they came to be working together, Iggy says, "I emailed Josh because he is young and beautiful and I thought it would be great to work with him."

Revealing an unusual hobby, Iggy says, "I didn't have much money until I was quite old so when I got some dough, I started collecting chairs and I sit in each of them every morning. It's somewhere to park my bottom."

Talking about the crowd diving he is responsible for inventing, Iggy says, "I don't do it all the time now as it's too rough." Josh interjects, "Iggy has the ability to ignore everything dangerous."

Asked if he is thinking of retiring, Iggy says, "I will step back at some point. Another album would be a big undertaking from an old git like me!"
