On 14th August 2012, celebrity photographer Oliver James L’eroe who is famous for his work with the likes of Lady Gaga, Little Richard, Sinead O’Connor and Yoko Ono tweeted the following:

— Oliver James L’EROE (@LEROE24) August 14, 2012
Excited by the news, two of our forum members contacted him via Facebook to learn more.
The first reply came from Nik_Strobe. You can read the full conversation on this forum post. According to his conversation with the photographer, the information comes from the organisers and their parties and he (L’eroe) seems to have no doubt that the information is accurate. L’eroe also emphasises that the tour will be huge, adding that they will be doing a stadium tour with the opening acts being “a MASSIVE surprise”. Although still just a rumour, The Prodigy and Underworld are told to be likely support acts for the tour.
The other reply comes from forum member Aeriform:
In his reply this time he mentions that he was getting some heat from the organisers of the Roskilde Festival in Denmark for the information he leaked which seems to confirm the rumours. When quizzed about dates he listed five big festivals in Europe: Roskilde in Denmark, Primavera Sound in Spain, Oyafestivalen in Norway, Glastonbury in England, and Peace and Love in Sweden.
Many on the forums are already sceptical of the new information and until we can confirm it from other sources, for now it is just speculation. Feel free to join in the discussion on the forums.
