Also Sprach Zarathustra Opus 30 Richard Strauss
What's in store on the BGT duo's hotly anticipated second album? Explore a selection of love songs - and a few Christmassy tunes thrown in to put you in a good mood!
Written by John Denver, Perhaps Love was originally recorded as a duet between him and Placido Domingo. Jonathan and Charlotte liked the song so much they've named their entire album after it, telling the story with every word.
"It's such a poignant, beautiful song." At least, that's how Jonathan described it, and we're inclined to agree. Putting their unique spin on a song performed by Sarah McLachlan and Josh Groban, Jonathan and Charlotte display their talent for a range of styles.
It's the first solo from Jonathan on the album, so expect some belting tenor notes and some passionate vocals. He first performed it at secondary school - where he first started lessons with singing partner Charlotte and the duo was born.
Citing Andrew Lloyd Webber as one of her favourite composers, Charlotte takes on this moving piece from Phantom of the Opera as her first solo. Expect tug-at-the-heartstrings cello solos and thick string accompaniment to accompany Charlotte's soprano tones.
Appearing in Once, this touching love song has been covered by a number of musicians since its release in 2006 - including Il Divo. Jonathan said: "I thought it would be a really great song - I'd already had designs on it to cover it myself, so I thought why not do this together, and go crazy… so we did!"
What do you get when you mix a 1986 song by Candi Staton with violins, harp, and Jonathan and Charlotte? It's quite a different take on the original, transforming the music into a string-fuelled poppy operatic number.
From 80s dance tunes to Neapolitan songs, it's Jonathan's turn for a second solo. He's described it as one of his favourite songs of all time: "It's so loud, there's so much energy, so much power within the song itself… it's a lot of fun to sing!"
"My dear beloved, believe me - without you, my heart languishes!" Charlotte takes on a pure classical love song, following in the footsteps of Cecilia Bartoli and Pavarotti.
From an impressive classical pedigree to an iconic pop track, originally performed by Diana Ross and Lionel Richie. This track's got it all: a drum machine, panpipes, and a hold-on-to-your-hats moment as Jonathan belts out a solo operatic passage. You've been warned.
"I wanted to take a pop song and chop and change and create something totally different from what it was before," Charlotte said. It sounds like she's managed it: her take on Roxette's famous track creates the ultimate classical crossover song.
A final solo from Jonathan, from Verdi's Nabucco. Recognise the music? It's also known as the 'Chorus of the Hebrew Slaves', performed by - you've guessed it - an entire opera chorus, so it's pretty unusual to hear the music as a solo.
Easing us gently into the Christmas spirit, this festive tune doesn't actually mention the birth of Jesus - although it's heavily implied! Although it seems like the music's been around for ever, it was actually only written in 1972.
Bringing the album to a close, this track's inspired by the duet by Placido Domingo and a young Charlotte Church.
