Answer the question at the end by quoting:

"Hey Jude" is a song by the English rock band the Beatles, written by Paul McCartney and credited to Lennon-McCartney. The ballad evolved from "Hey Jules", a song McCartney wrote to comfort John Lennon's son, Julian, during his parents' divorce. "Hey Jude" begins with a verse-bridge structure incorporating McCartney's vocal performance and piano accompaniment; further instrumentation is added as the song progresses. After the fourth verse, the song shifts to a fade-out coda that lasts for more than four minutes. "
Scott, Martin and the Beatles mixed the finished recording at Abbey Road. The transfer of the Trident master tape to acetate proved problematic due to the recording sounding murky when played back on EMI's equipment. The issue was resolved with the help of Geoff Emerick, whom Scott had recently replaced as the Beatles' principal recording engineer. Emerick happened to be visiting Abbey Road, having recently refused to work with the Beatles any longer, due to the tension and abuse that had become commonplace at their recording sessions. A stereo mix of "Hey Jude" was then completed on 2 August and the mono version on 8 August.  Everett writes that the song's "most commented-on feature" is its considerable length, at 7:11. The precedent for issuing such a long track on a single had recently been set by Richard Harris' hit recording of "MacArthur Park", the composer of which, Jimmy Webb, was a visitor to the studio around this time. According to Webb, Martin admitted to him that "Hey Jude" was only allowed to run over seven minutes because of the success of "MacArthur Park".  In the song's final bridge section, at 2:58, the spoken phrase "Fucking hell!" appears. Scott admits that although he was told about it, he could not hear the words originally. Lennon attributed the expletive to McCartney, according to Emerick, who reports Lennon's comment in his autobiography: "'Paul hit a clunker on the piano and said a naughty word,' Lennon gleefully crowed, 'but I insisted we leave it in [at Trident], buried just low enough so that it can barely be heard. Most people won't ever spot it ... but we'll know it's there.'" Womack considers that the expletive was actually uttered by Lennon. Malcolm Toft, the mix engineer on the Trident recording, also attributes it to Lennon. In Toft's recollection, Lennon was overdubbing his harmony vocal when, in reaction to the volume being too loud in his headphones, he first called out "Whoa!" then, two seconds later, swore as he pulled the headphones off.

Was there anything in the song that caused a controversy?

IN: Late Night with Jimmy Fallon is an American late-night talk show hosted by comedian Jimmy Fallon. The hour-long show, which premiered on March 2, 2009, and ended on February 7, 2014, aired weeknights at 12:35 am Eastern/11:35 pm Central on NBC in the United States. The third incarnation of the Late Night franchise originated by David Letterman, the program originated from NBC Studio 6B (and Studio 6A for the final 6 months of its run) in the GE Building at 30 Rockefeller Center in New York City.

The incorporation of the Internet was an innovation decided long before the show began. Highlighting interactivity, Fallon dove into the Web prior to the show premiering, creating a Twitter account and beginning a vlog on the show's official website, which ran snippets of comedy bits and background reports on how he was building the show. The show's Web site was staffed by three full-time bloggers, who compile viral videos and post photos. Questlove tweeted during tapings of the show. "I think a lot of shows don't use the Internet as well as they could," said Fallon in 2009. "The Internet has been awesome," he added. "They've got my back."  Online interaction and its presence on the show were crucial to its success. Fallon devoted considerable time and resources to incorporating digital ideas into his comedy -- "he sits at his desk behind a Mac, not a microphone" -- focusing especially on social media, which connects the younger audience.  Fallon published a welcome video for the Late Night YouTube Channel in May 2013; the channel featured segments such as "Ask Jimmy," "Night News Now," and "Web Exclusives." Many of the videos received a very high number of views, including the ""#Hashtag" with Jimmy Fallon & Justin Timberlake" clip that had garnered over 17 million views by October 21, 2013. During the open letter controversy between musical artists Miley Cyrus and Sinead O'Connor, the channel published an a cappella version of Cyrus' song "We Can't Stop" on October 8, 2013, in which Fallon and The Roots also perform.
