Today's More Rosebud is an unexpected April treat from the great comedian Harry Hill. You'll know Harry from his brilliant TV shows like TV Burp and Alien Fun Capsule or his podcast Are We There Yet? but you won't know about his incredible life.

Today Gyles speaks to a remarkable person: Sir Grayson Perry. Artist, presenter, thinker and fashion icon, Perry is a unique figure who has led an unusual life.

Gyles really enjoyed meeting this week's guest, Ed Balls, because he enjoyed bonding over their shared experience of Westminster.

Dame Kristin Scott Thomas is one of our best, most distinctive, and most watchable actresses, and we're delighted that she's our guest on Rosebud today.

In another special episode dedicated to the how, what and why of memory, Gyles talks to his long-time friend and colleague Professor Brett Kahr. Professor Kahr is a practising psychotherapist and an expert on Sigmund Freud, the father of psychotherapy and the inventor of the "talking cure".

Gyles is talking to one of his favourite comedians in today's Rosebud - Josh Widdicombe. Josh tells Gyles about his early days growing up in Devon; about his charismatic father, his clever mum, and his chain-smoking grandmother who lived next-door and delighted him with tales of her acting days.

Rosebud is thrilled to present to you one of the truly great Hollywood actresses of her generation: Sigourney Weaver. Known for her groundbreaking performances as Ripley in Ridley Scott's Alien movies, Sigourney redefined what women could do in the movies.

Tariq Ali is one of the most famous and recognisable figures of the revolutionary student movements of the 1960s. In his distinctive red Aquascutum mac he led marches, gave speeches and galvanised opposition to the Vietnam War and other big issues of the time.

Sir James Dyson talks to Gyles about his remarkable journey: from academic under-achiever to one of the world's most successful inventors and businessmen.

It's Valentine's Day, and we at Rosebud knew we needed to find someone special, to spread the love to you, our gorgeous listeners: we needed to find our very own Rosebud Romeo. Who better than possibly the most charming actor of them all: Nigel Havers?

Mark Gatiss: actor, writer, producer, director and creator - this is someone who makes Gyles Brandreth look like an under-achiever! From The League of Gentlemen, to Doctor Who, Sherlock and the Christmas Ghost Stories, Mark has been behind some of the most distinctive and original television of recent times.

In this episode, Vanessa Feltz wows Gyles with some of the funniest stories he's ever heard on Rosebud: from a first kiss with Pete Tong by the pool in Lanzarote, to an illicit encounter with a stranger who was bowled over by the magnificence of her bosom... this show is full of laughs and brilliant anecdotes.

In this episode of More Rosebud, the hypnotist and self-help writer Paul McKenna talks to Gyles about a subject you may have heard about before on Rosebud: manifesting.

Krishnan Guru-Murthy has been presenting the news on Channel 4 since 1998, but his career began long before that, when he was only a teenager. In fact, Gyles is a bit jealous when he finds out that Krishnan was even younger than him when he first appeared on TV!
