As I can see Jeff Lynne has hired most of the players for his "come back"!

The success of the Children in Need was followed by BBC Radio 2's DJ Chris Evans, who asked his listeners if they wanted ELO to perform. The 50.000 tickets for the resulting BBC Radio 2's "Festival in a Day" in Hyde Park on 14 September 2014 sold out in 15 minutes. Billed as "Jeff Lynne's ELO", Jeff Lynne and Richard Tandy were backed by the Take That/Gary Barlow band from the Children In Need concert, led by Mike Stevens and the BBC Concert Orchestra. Chereene Allen took to the front line with the band. The development of modern digital processing added a smoother finish than previously, which has led Jeff Lynne to reconsider his preference for studio work, hinting at a UK tour in 2015.

On 8 February 2015, "Jeff Lynne's ELO" played at the Grammy Awards for the first time. They performed "Evil Woman", then "Mr. Blue Sky" with Ed Sheeran, who introduced them as "A man and a band who I love".

On 10 September 2015, it was announced that a new ELO album would be released. The album was to be under the moniker of "Jeff Lynne's ELO", with the band signed to Columbia Records. Alone in the Universe was released on the 13 November 2015. The album was ELO's first album of brand new songs in nearly 15 years. The first track, and single, "When I Was a Boy" was made available for streaming on the same day and a music video for the song was also released. A small promotional tour followed the album's release which saw ELO perform a full concert for BBC Radio 2 along with ELO's first two shows in the United States in 30 years, both which sold out very quickly. ELO also made rare U.S. television appearances on The Tonight Show Starring Jimmy Fallon, Jimmy Kimmel Live and CBS This Morning. A 10 date European tour was announced for 2016.

On 14 September, 2014, "Jeff Lynne's ELO" accompanied by the BBC Concert Orchestra and backed by Take That/Gary Barlow band, headlined BBC Radio 2s Festival In A Day in Londons famous Hyde Park. The show marked the first time in almost 30 years that ELO had performed on a festival state. 50.000 tickets for the event sold out in a matter of minutes. The release also features interviews from the performance along with the documentary Mr Blue Sky - The Story Of Jeff Lynne and ELO.
