Sam Smith has joined forces with Alicia Keys on a new version of their hit I’m Not The Only One.

Originally featured on their debut album ‘In The Lonely Hour’ (2014), Sam has reworked the ballad to feature the No One singer for the 10th anniversary edition, which is out now.

Alongside a photo of the pair, Sam wrote on Instagram: “I’m Not The Only One feat. the truly incomparable @aliciakeys. Coming Friday August 2nd.

“I am so honoured to have such an incredible talent and a beautiful soul join me on this track to celebrate a decade of In The Lonely Hour.”

For the new edition of the LP, Sam re-recorded Stay With Me with updated lyrics, admitting the meaning of the song “changes” for them every time they listen to it.

“When me, Jimmy and Tourist wrote this song, none of us would’ve expected it to become what it has in the world,” Sam shared in a letter to fans. “I will never forget Will (Tourist) playing those three chords on the piano. I stopped everything I was doing and said ‘what is that’.

“Those chords and this song still stir me in the same way to this day. I’ve never once got sick of singing it.

“The meaning of this song changes for me whenever I sing it. The words ‘Stay With Me’ can mean a million different things and follow me throughout my life like an old friend.”

The revised song sees Sam change the lyric ‘I’m just a man’ to ‘baby understand’, in line with their live performances in recent years. Sam added: “This song is truly so special to me, so for the 10 year anniversary I re-recorded the track, which will be available on all platforms and physical, including the updated lyric ‘but I still need love, baby understand’ which felt really important to me.

“It’s beautiful to know that sometimes, we can change the past.”

‘In The Lonely Hour’ peaked at No. 1 in the UK and went to No. 2 on the US Billboard 200 upon its release.
