Blondie's Debbie Harry talks to BBC Breakfast about appearing on stage with the band and how they have all stayed together after forming in the late 1970's.
She will be appearing alongside The Who, Jeff Beck, Bryan Adams and the Verve's Richard Ashcroft as part of a concert to raise money for The Killing Cancer Charity.
The charity funds research into a therapy called Photodynamic Therapy (PDT) which uses laser light to activate cancer drugs within the body.
