I can't imagine how it feels to be him.
Dermot Kennedy has admitted to feeling "overwhelmed" a couple of times in the last year while performing.
"99% of the time I absolutely love it and don't feel nervous at all," he wrote on Discord.
"I have had one or two times in the last year where I felt a little bit overwhelmed, in which case it's a pretty intimidating situation to be in, even though it's so supportive. But pretty much every time I feel good up there."
But sometimes, these gigs can be "frustrating" as he wants the audience to understand how grateful he is for their support.

"Sometimes I'm standing on stage and it hits me," he said.
"Like in Atlanta for example, in my head I'm just thinking, 'this is so insane. There are thousands of people here because they like the music I made.'
"It's kind of frustrating sometimes in a way, because I would almost like to chat about all of it with everybody and fully express my gratitude, cause it's the most amazing thing in my life and I appreciate it so much."
Dermot acknowledged that chatting with every fan in the audience would be "impossible," and so he tries to give his thanks by playing the best show he can.
He said he wants to "give people the most honest, hopefully powerful experience I can give them, no matter where I am.
"The people that are there like my music, so technically that's the best thing I can offer."

Where is Dermot playing next?
Dermot is getting ready to play three nights at Thomond Park this weekend, and seems to be buzzing about it.
"To be able to play to 30,000 people three nights in a row, is something that is hard to process and was very hard to believe one day," he said on Instagram.
If you fancy making the trip, there are still tickets for the gigs on Friday and Sunday!
