Famous people could be congratulating you for throwing your rubbish away responsibly in talking bins。
The bins will be installed in central London and Liverpool in October。
Actress Amanda Holden has recorded a message saying "Yes! Do that again!" and former cricketer Phil Tufnell calls out "Howzat!"
The Liverpool bins feature Mike McCartney singing a re-recorded version of the Scaffold hit "Thank You Very Much"。
The song, which will have the new line "thank you very much for binning your litter", will come from two bins installed in the city's Mathew Street。
Some of the London bins will also burst into song when litter is thrown into them, with tunes including I'm Singing in the Bin and Rubbish Keeps Falling on my Head。
Others who have recorded messages include the voice of the X Factor, Peter Dickson, comedian Gina Yashere, rugby player Kenny Logan and opera singer Janis Kelly。
The project has been created by Keep Britain Tidy in partnership with Liverpool City Central BID and the arts organisation Sing London。
Additional messages will be adapted to suit each location, the organisers hope。
For example, Covent Garden's bin is operatic and the bin by Lord's Cricket Ground is filled with sport-related sounds。
The bins will be installed from 13 October and the ones in London will remain in the capital for two months, after which time they will tour the UK, returning for the Olympic Games in 2012.
If successful, they could become a permanent fixture。
