One half of Dave's own Taskmaster - Alex Horne - has a side career: he's the leader of a band called The Horne Section. They've already performed with some of the biggest names in music and comedy and now they've scored their very own two-hour special featuring Alex and the band's spontaneous and free-wheeling combination of live music and comedy. Recorded at the London Palladium, the jazz/comedy hybrid features guest performances from Nadine Coyle, Sue Perkins, Sara Pascoe and Joe Wilkinson.

With Greg Davies' permission, Alex Horne finally gets the chance to pitch his own TV show alongside his band. Rehearsals get underway, while family friend Thora tries to relax in the room next door.

Showtime is fast approaching. As Alex and the band prepare for the live pilot, Martin Kemp demands to sing an original song, Anneka Rice appears, and John Oliver is desperate to be on the show.

Despite overwhelming backlash on Twitter following the pilot, Alex and the band get the green light for a full series. Can they win over the youth with the help of celeb guest Dr Ranj Singh?

Just as they're about to go on air with Big Zuu, Alex is thrown by some unexpected news but tries to keep it together to please the TV execs. Unfortunately, the bassist is stuck in Alex's warehouse.

Still under pressure to impress, will Alex's musical mates put up with his ridiculous requests? John Oliver secures a performance from Imogen Heap, who appears with tribute band The Horne 'Selection'.

A lonely Alex tries to mend his friendships and calls on celebrity psychologist Ken to help get the band back together. With Thora back on set, can they make their final episode the best one yet?

Following an unsuccessful TV appearance, Alex is eager to prove himself. Thora books multi-instrumentalist Reggie Watts as a guest on the show, while Alex spots an opportunity in Ash's new commission.

Alex has won a big award! This calls for an acceptance speech in his trademark style. But with Ash's birthday speech and a monologue still to write for tonight, the pressure's on.

Somehow The Horne Section TV Show is still on air, and everyone is excited about this week's special guest, Victor Flamencito... until something terrible happens on set. But the show must go on!

The Horne Section TV Show collaborates with Europe’s Most Haunted House to produce the spooky ‘The Europe’s Most Haunted House TV Show’. But Joe’s worried his haunted bald patch might cause problems.

There’s palpable excitement when the Pope is booked as the show’s special guest. Meanwhile, everyone is impressed by Gemma the new work experience girl - especially Nelly. Can love blossom on set?

Everyone's distraught when Reggie's summoned back to the US - he was the only good thing about the show! Can Alex step up to lead the band? And will Lucy finally do some work?
