The Lonely Hearts Club Tour

The Lonely Hearts Club Tour is the second concert tour by Welsh singer-songwriter MARINA (formerly known as Marina and the Diamonds).
Background and development.
The UK dates were announced on Valentine's Day with the North American dates announced in April. On 30 April 2012 it was announced that the UK segment of the tour has been rescheduled due to vocal cord condition of the artist to dates beginning on 18 June 2012. The tour ran concurrent with Coldplay's Mylo Xyloto Tour for which Marina served as an opening act. On Monday, 11 February 2013, Diamandis announced via her website and e-mail, that her European tour was cancelled. On Saturday, 4 May, Diamandis debuted the track "Electra Heart", as an interlude to her final, closing leg of the tour.
