 On 10 December 2007, Led Zeppelin reunited for the Ahmet Ertegun Tribute Concert at the O2 Arena in London, with Jason Bonham again taking his late father's place on drums. According to Guinness World Records 2009, Led Zeppelin set the world record for the "Highest Demand for Tickets for One Music Concert" as 20 million requests for the reunion show were rendered online. Music critics praised the band's performance and there was widespread speculation about a full reunion. Page, Jones and Jason Bonham were reported to be willing to tour, and to be working on material for a new Led Zeppelin project. Plant continued his touring commitments with Alison Krauss, stating in September 2008 that he would not be recording or touring with the band. Jones and Page reportedly looked for a replacement for Plant, considering singers including Steven Tyler from Aerosmith, and Myles Kennedy of Alter Bridge, but in January 2009 it was confirmed that the project had been abandoned. A film of the O2 performance, Celebration Day, premiered on 17 October 2012 and was released on home video on 19 November. The film grossed $ 2 million in one night, and the live album peaked at number 4 and 9 in the UK and US, respectively. Following the film's premiere, Page revealed that he had been remastering the band's discography with the first three albums re-released on 2 June 2014, containing bonus tracks.
