• This was the third Olly Murs single following "Heart On My Sleeve" and "Heart Skips a Beat" to feature the blood-circulating organ in its title. It was released as the lead single from the singer's special re-issue of his third studio album Right Place Right Time.
• Olly penned the song in collaboration with Tom Barnes, Wayne Hector, Iain James, Pete Kelleher and Ben Kohn. During his RPRT Listening Party on UStream, he said this was the last song he wrote in the studio, he loves the melodies and it's his favorite song on the record.
• The video is an almost a shot-for-shot remake of Robbie Williams' 1997 clip for "Angels." The black-and-white promo was directed by Vaughan Arnell - who also shot the original Angels visual. Murs is seen in the same locations as the original video and Williams - who was joined by Murs on his Take The Crown tour - makes a cameo appearance. Speaking of the vid, Robbie stated: "Imitation is the highest form of flattery. I am easily flattered, and I love Olly. We always have a good time together and this was no exception."
• When Murs arrived at the session, the songwriters already had this song half-written, and they played it to him. The six of them then quickly completed the tune.
• Murs recorded a new version of the tune for its single release. He told Glamour magazine: "We wanted to change the intro to the song and add more strings and backing vocals."
