'Falling Slowly' from Once | Carrie Hope Fletcher and Jamie Muscato

Watch a special performance of "Falling Slowly" from Once ahead of the concert performance of the show at The London Palladium.

The show, which reunites Carrie Hope Fletcher and Jamie Muscato after their time in the award-winning Heathers, was announced last year and met with significant public demand.

Once is based on the 2007 film of the same name, and follows a disillusioned busker whose life is changed forever when he has a chance encounter with a woman who needs her vacuum cleaner fixed. It was first seen in the US in 2011 ahead of a Broadway run from 2012. It went on to win eight Tony Awards, with a West End premiere following in 2013.

With music and lyrics by Glen Hansard and Markéta Irglová and a book by Enda Walsh, it will play for two performances at 3pm and 7pm on Sunday 12 March.

Joining Fletcher and Muscato are Phil Adèle (ø) as Eamon, Kamilla Gregorovitch (The Grammar of Witchcraft) as Reza, Seán Keany (The Choir of Man) as Billy, Alasdair Macrae (The Strange Undoing of Prudencia Hart) as Da, Loris Scarpa (Rapunzel) as Svec, Jos Slovick (Beautiful) as Andrej, Christina Tedders (The Lion, the Witch and the Wardrobe) as Ex-Girlfriend, Angus Tikka as Bank Manager, Susannah Van Den Berg (101 Dalmatians) as Barushkaand Michael Vien as (making the professional debut) as Emcee.

Tabitha Storton will play Ivonka at the matinee show and Mia Raggio will take the role at the evening performance.

Dean Johnson directs the show (which is cast by Emma Norman from Maven) with musical direction by Adam Hoskins.

My Heathers heart is fluttering seeing them again!!!

They absolutely smashed it, it was the most beautiful and magical evening. I'd love a full production of Once with Carrie and Jamie.

Carrie always seems to have so much chemistry with whoever she sings with, but especially here, the eye contact throughout is just so beautiful and you can tell there's so much support there both ways. Ugh love this a lot

[UncleT-wony]

Harmonies are absolutely spot on. Harmonies can make or break a song, but Carrie smashes it out the park again, no problemo 😉👍

[RhoadesLessTraveled]

Their voices are so perfectly fit for a song like this. Very glad we got a taste of the concert. Wish I could have been there. ❤

This is absolutely magical. Their voices were made for one another. Can't wait for the concert!

For a second I thought I'd already heard this, and then it hit me that I'm remembering a deep search of youtube and finding old footage of her covering this on a stage performance. Some old phone recording or something. Pre youtube career days. If you go looking for it, know that it's a deep search to find. Pretty sure it was this song. But there were a couple songs sung at the time if you find them. Old relics

"mom and dad" me about two people barely older than me

[mrcblaser]

One of the best songs from a musical. Eva!

[sallycircle]

I actually cannot cope. This was sung at my wedding when my new husband and I signed the register. And now...my two favourite actors. I wish I could go to the concert. 😭😭💚🧡💚

[DanishGirl]

I heard this song the first time 10 years ago when carried did a cover on her channel it's so weird that I now get to hear this version so many years later

[lauratheartist]

Oh my gosh they’re back AHHHH I can’t wait for this! Please let this be recorded I’d pay to watch a recording of this.

[notimeforthis]

i can't wait to see these two reunited on stage!

[SamWest]

We've come a long way since Carrie sang this with her friend Ant. It's exciting to get to see a snippet as I won't be able to get to the performance

[Showtunediva]

I love this song even more because Carrie’s voice is so beautiful!😀

[embemp]

Pure magic. Such a talented duo. Love Carrie’s dedication of playing the piano for this role. Looking forward to the concert.

[Mcflymad]

So so so wish I could go to this concert!! Saw them both in Heathers and it was heaven - if they do another show together again IM THERE

[LauraDavisOfficial]

This is actually incredible! ❤❤ I am so excited for the concert

[sarahleete]

Saw them sing this in her Letters tour in Guildford. It was superb.

[belleroseanthousis]

This was the most beautiful thing I’ve ever listened to 😍😍xxx
