London CNN  — 

British pop singer Rebecca Ferguson says she has been invited to perform at Donald Trump’s inauguration, but her response may not be the RSVP the President-elect’s team were expecting.

The former UK X-Factor runner-up said she would only accept the invitation on the condition that she could perform “Strange Fruit” – a song protesting racism in 1930s America, made famous by Billie Holiday.

Rebecca Ferguson was the runner-up of the UK's X Factor in 2010.

In a statement posted to the singer’s Twitter account on Monday night Ferguson said: “I’ve been asked and this is my answer. If you allow me to sing “strange fruit” a song that has huge historical importance, a song that was blacklisted in the United States for being too controversial. A song that speaks to all the disregarded and down trodden black people in the United States. A song that is a reminder of how love is the only thing that will conquer all the hatred in this world, then I will graciously accept your invitation and see you in Washington. Best Rebecca X”

The lyrics, written in the 1930s by Jewish communist Abel Meeropol, were composed as a protest poem to highlight endemic racism in America’s southern states.

The song’s opening lyrics deal with lynching, which was still happening in parts of the country at the time: Southern trees bear strange fruit // Blood on the leaves and blood at the root // Black bodies swinging in the southern breeze // Strange fruit hanging from the poplar trees.

According to Billie Holiday’s Estate, Holiday regularly performed the song at live performances in 1939. Her record label, Columbia, refused to let her record the song under their name, so they granted her a one-session contractual release that gave Holiday clearance to independently record the track.

Later that year, the album featuring “Strange Fruit” sold a million copies, becoming Holiday’s biggest-selling record at the time. In 1978, the single was inducted into the Grammy Hall of Fame.

In 2015 Ferguson released her third album, “Lady Sings the Blues,” featuring covers from Billie Holiday’s record of the same name. “Strange Fruit” was not featured on Ferguson’s album.

Ferguson’s rep told CNN that she had no further comment.

Trump’s transition team did not return a request for comment at the time of publishing.

So who will perform?

With less than a month to go, the inaugural committee has announced three acts so far: the Radio City Rockettes, the Mormon Tabernacle Choir and 16-year-old “America’s Got Talent” star Jackie Evancho.

But in this small group of performers, there’s no shortage of controversy.

Last week, a member of the Mormon Tabernacle Choir – a group who has previously performed at five presidential inaugurations – quit, stating that the performance for Trump would betray her values.

Earlier in December, the Madison Square Garden Company released a statement saying individual dancers from the Rockettes wouldn’t be compelled to participate at the inauguration after Phoebe Pearl, a dancer with group, reportedly protested on Instagram about the group being chosen to perform at the event. Her post has since been deleted.

In November, Elton John refused an invitation to perform at the inauguration, denying a claim made by a vice chair of Trump’s presidential inaugural committee.

Last month, The Beach Boys told CNN that the group has been contacted about performing, but that “no decision has been made at this point as to how or whether they will participate.”

In a Twitter post last month, Trump said that he wanted “the PEOPLE” at the inauguration – not “so-called “A” list celebrities.”

At Barack Obama’s 2009 inauguration, Beyonce, Aretha Franklin, James Taylor, Brad Paisley and Alicia Keys performed.
