Yasser presents this edition of the Official Chart Show.
The Vamps cause havoc in the studio as they take on a High 5 challenge, try their hand at presenting and even attempt to help out backstage.

The videos that viewers have chosen for this week's playlist are revealed, and Greg James joins Yasser to countdown the UK's Official Top 10. Show less
