Paul Mescal featured in Dermot Kennedy's 'Some Summer Night' live stream performance from London's Natural History Museum on Thursday night.

Kennedy and Mescal blew fans away with their performance of 'Giants' as part of Kennedy's 'Some Summer Night', a special one-off live performance broadcast on YouTube. 

Some Summer Night was Kennedy's first live show since his sell-out tour in America and the Irish music star stunned fans with his return. 

This is it. This is the tweet. @DermotKennedy & @mescal_paul 💚🇮🇪

Mescal, who stole hearts as Connell from 'Normal People', read poetry between each of Kennedy's songs and in addition to joining Kennedy to sing his new song "Giants."

The performance sent fans into meltdown on Twitter. 

"Is there no end to your talents @mescal_paul," one fan wrote on Twitter.

One fan said that Mescal and Kennedy was the combination they didn't know they needed, while another poked fun at the recent British press attempts to claim Mescal as one of their own.

The following morning, Kennedy thanked fellow Irishman Mescal in a tweet for collaborating with him:

Getting to collaborate with other like-minded souls is truly an honour. I can’t thank you enough for lending your voice, your talent and your heart to that night @mescal_paul 🇮🇪 X

It seems the two may have had a round of celebrations after the outstanding performance, however:

I’m I’m unavailable atm due to a severe headache
