“Cans and straws and apple cores” runs the song on this CD, introducing a litany of litter on London’s streets. Pick It Up is the story about persuading adults not to be environmentally irresponsible and dirty. After learning the song and undertaking never to be so messy themselves, children can register as Litter Detectives, like those in the story. Pick It Up (book and CD) costs pound;5.95 and can be bought from bookshops and Sainsbury’s in London or ordered from the website www.pickituplondon.com, where you also register as a Litter Detective.
