Yeah Bono is pretty active but there are lots of people who do charity work and give money that remain unknown I guess it might be a little harder when your famous idk??
Elten John I think.Michael Jackson too.He had a castle or something build for children.And he is no child abuser,those are just rumors made by the media.He loves children.Normal love.So stfu xD (I am not a fan,but I know...I know all...muwhahaha xD)
P!INK is also a charity person.She is one of the few who stopped the seal massacre with that bloody sport.Although she is not rock.
