All Together Now is the BBC's latest singing contest, with a £50,000 cash prize up for grabs.
Contestants perform for a giant judging panel made up of 100 singers called The 100, willing them to vote with their voices, and stand up and join in.
The greater the number that stand up and sing along, the higher the act’s score.
Headed up by former Spice Girls' star Geri, The 100 are made up of specially cast members of the public from across the UK, all with a real mix of music backgrounds and singing credentials.
This weekend the heats continue as musical theatre performer Ben chooses to sing the Spice Girls’ anthem, Goodbye, on All Together Now.
He introduces it saying "I’m a huge fan of 90’s music, and I think this song will have a connection with one of you in particular," looking at Geri.
As he sings Geri has tears in her eyes and can be heard saying ‘that was quite ‘ouchy’ and ‘I’m really sad’.
She asks: "Ben, do you know what the history behind that song is?"
He replies: "I thought it was the message that they had to you when you left the band."
Geri carries on: "Yeah, that’s right. So when I left the band it was really sad and it completely brought me back to that moment, bringing all those feelings back."
Ben finishes: "That song, it meant a lot to Geri, but it meant a lot to everyone else in that era, at that time."
All Together Now airs Saturday at 7:20pm on BBC One
Elsewhere in this week's episode, hopefuls include a medical student, an HR manager, and firefighting brothers. The acts will perform tracks by Paloma Faith, Christina Aguilera, Queen, Radiohead, OutKast and Stevie Wonder.
Who will get TV’s biggest judging panel, up on their feet and singing along, and which two talented acts will secure their place in the grand final for £50,000?
