Pick of the weekend

All Together Now, 7.30pm Saturday, BBC One

Slag this show as much as you like - and many do - but its upbeat mix of popular tunes, big smiles and party atmosphere is obviously a big hit, because it's back for a second run.

Hosted by Rob Beckett, this is a talent show where any kind of singer can take to the stage, from soloists to groups, amateurs to professionals, but they all have one goal - to win over TV’s biggest judging panel, The 100.

Headed up by Spice Girl Geri Horner, The 100 are a mix of music industry singers, such as Divina De Campo, Georg, Paulus, Tina T, Mr Fabulous and Lili. They'll be joined this year by some new faces.

In this first episode, acts take on classic hits by the likes of Amy Winehouse, Chaka Khan and Led Zeppelin and contemporary hits by Shawn Mendes, Camila Cabello, Rudimental and James Morrison.

Soft Cell: Say Hello, Wave Goodbye, 9.00pm Friday, BBC Four

2018 marked the 40th anniversary of Soft Cell, one of the most charismatic bands in the history of popular music. To celebrate this landmark, Marc Almond and Dave Ball reunited for an emotional farewell concert at London’s O2 Arena.

With unprecedented access, this film provides an intimate portrait of the band, following rehearsals as well as footage from the actual concert, woven in with archive and music videos.

The film also documents Marc Almond’s formative years growing up in Southport and Dave Bell’s in nearby Blackpool, and how the two met as art students at Leeds Polytechnic in the late 1970s.

Soft Cell burned brightly between 1981 and 1984, Almond then enjoyed a successful solo career, and this documentary retraces the duo's steps, right up to their final performance, at the O2.
