Elephant" The album's
lead single, "Elephant," features DJ and co-producer
Erick Morillo. Following several delays, the song was released on 9 March 2012, in both physical and digital formats, with each version including remixes of the track. Music critics gave the song mixed reviews, with disagreements about its production, sound, and Burke's performance. Commercially, it was a success in the UK, peaking at number three on the UK singles chart, her second-highest performance to date. In early April 2012, a
music video was released showing the singer and
backup dancers having fun while performing in an underground facility. "Let It Go" was the album's second single, released on 22 May 2015. The digital formats featured several remixes of the single. The track received mixed reviews, with some citing production issues and a lack of originality. However, some critics praised its catchiness. Commercially, the single underperformed in the UK, peaking at 33 on the UK singles chart, her lowest-performing single to date. Burke originally planned a third single with a male artist. However, the idea never materialised, and plans were abandoned. Burke promoted her album by appearing on several television and live shows. Burke first performed "Let It Go" on
The Voice of Ireland season finale on 29 April 2012, and on
Lorraine, a
breakfast television show in the United Kingdom, on 22 May 2012, where she also gave an interview about the song and
Heartbreak on Hold. Burke then performed an acoustic version of the title track "Heartbreak on Hold" on the daytime talk show
Loose Women. She played a live acoustic set in Le Mans, France, on 15 June 2012, and at Signal 1's Stoke 2012 Live festival weekend the next day. Burke recorded four songs in front of a small crowd for an event called "An Audience with Alexandra Burke". That Grapejuice recorded the performance and uploaded it on their website. Burke performed at
Manchester's MEN Arena on 19 July 2012, and again at Liverpool Arena for
Radio City Live 2012 on 21 July. One day later, Burke appeared on
KEY 103 Live in Manchester alongside
One Direction,
Rizzle Kicks,
Little Mix and
Will Young, as well as at Party in the Park in Leeds. Burke gave a concert in London's
Hyde Park on 2 August as part of
BT's London Live celebrations of the
2012 Summer Olympics. On 15 September, Burke headlined Scotland's Youth Beatz music festival. ==Critical reception==
