The Chemical Brothers' Tom Rowlands told Billboard regarding this ode to togetherness in the age of Brexit, "The song makes us emotional with its feeling of love and brotherhood / sisterhood without boundaries."
The song features a sample of the New York poet Michael Brownstein talking about a love where there is no need for boundaries between nations.
"Piano Man" was inspired by Billy Joel's time playing at a piano bar in Los Angeles. The "real estate novelist" was a guy who always talked about writing a book, but spent all his spare time in the bar.
"Lean On" was originally sent by Major Lazer to both Rihanna and Nicki Minaj's camps as a slower reggae track. After both parties rejected the tune, Major Lazer recruited Danish singer MØ to supply vocals and recorded it themselves.
