In this second episode, acts perform tracks from music icons including Freddie Mercury and Shirley Bassey and contemporary artists such as Bruno Mars and Zayn Malik. Every act must deliver if they want to get The 100 up on their feet and joining in. There's loads of humour from Rob, memorable performances and tough critique from Geri and her fellow judges. Who will get them up on their feet and singing along and which two acts will secure their place in the grand final for £50,000?
