Hundreds of tango dancers will dance silently on London's bridge and railway stations during the evening rush hour on 7 July, four years on from the London bombings.
TangoCommute is a participatory dance event – open to all – which took place for the first time last July.
Railway station concourses and Thames bridges become dancefloors as couples silently dance to music via their iPods.
Earlier this month a 'pre-TangoCommute' event was held on Blackfriars Bridge by members of the Che Tango group.
"This year my group is representing tango through the generations," says Michele Stanley.
"TangoCommute aims to bring a sense of compassion and passion for peace to commuters who were so sadly decimated on the seventh of the seventh 2005.
"People like us will be dancing on the stations and bridge of London."
"This is a pre-TangoCommute with its own message that not only are the older tango people passionately concerned about peace in our time but also the young. This is why we dance among the commuters."
