Corporate concerts are a weird beast. The pop stars at them are usually flown in from overseas to spruik a brand and perform to a small crowd, many of whom don't always know who they are.
And so the corporate gig put on by Microsoft on Thursday night for those who lined up at the company's first Australian store on Thursday for free tickets to see Jessie J (or just visit the store) was no different.
As the singer said herself: "These gigs are really awkward, hey? It's really quiet and everyone is in a chair and it's really chilled. It's really fun and yet awkward." 
But not everything went to plan as the British pop star and The Voice Australia judge performed at the concert, held at Sydney's State Theatre on Thursday night.
Not only was the "Domino" and "Do It Like A Dude" singer forced to perform acoustically (much to her displeasure) with one of her best friends, but she also had to entertain a crowd who barely knew her.
"So how many of you here have ever seen me sing live before?" she asked, to which about ten teenage girls sitting in the front row screamed that they had.
"Great, ten people," Jessie joked. "Woo."
Curious and perhaps a little flabbergasted, the singer asked the question in reverse, inquiring how many people had never seen her perform live before, to which almost everyone in the audience put their hand up.
"I don't know whether I should've asked that," she responded, laughing nervously. "Now I feel, like, pressured."
She later added while singing a song: "So I know that not everyone in this room is going to admit that they've ever needed this song or this moment right now.   Maybe you'll start crying and you didn't even know you needed to cry. Or you'll cry because you hate me and you hate my voice and you wish it was over because someone made you come with them because they didn't want to go by themselves. I know. You hated me on The Voice and now your girlfriend's got you here and you hate me now. It's just awful. You want it to be over. "
Which prompted her fans to comfort her, to which she responded: "I'm joking! It's OK. Seriously."
But was she? It was hard to tell, with her later adding: "I'm very aware that there is a lot of people in Australia that don't like me and that's OK."
The singer certainly didn't disappoint her fans ??? even if there were only ten ??? but it was clear she was personally disappointed that her band couldn't be on stage with her.
"Tonight was supposed to be myself and my full band and for whatever reason that wasn't able to happen tonight," she said.
"I always feel like everything is for a reason, right? This is my first ever acoustic gig that is like more than 100 people."
And it wasn't only her who was disappointed. As this reporter overhead one person in attendance say: "If I'd known it was going to be acoustic I would have stayed home."
This reporter had the opposite view, finding her voice stunning, especially when she brought out The Voice Australia winner Ellie Drennan on stage to sing with her.
Most of those who were there (about 1500) received one of the free 750 double pass tickets to see the singer perform at the Microsoft-funded concert. They got their tickets by lining up at Microsoft's Pitt Street Mall store opening midday Thursday.
That much was clear when Jessie inquired what someone (Bazil) did as his day job, to which he responded that he "queued for free stuff", causing the theatre to erupt into laughter.
A further question uncovered that Bazil had brought a girl (Erica) along with him, who he was on his tenth date with.
"It's date night and you took her to the free stuff!" Jessie exclaimed, before dramatically falling to the stage floor in disbelief.
But perhaps the corniest (yet also sweetest) moment of the night was was when Jessie randomly picked a fan to sing on stage with her. And who did it end up being?
The daughter of Microsoft Australia's managing director Pip Marlow, Lucy, aged 11.
When Lucy was picked, many Microsoft employees sitting at the back of the theatre (including Marlow) couldn't believe it. It seemed as though her being picked out of the audience was truly random, although being in the front row probably had something to do with it.
Throughout the entire evening Jessie was able to turn a crowd of nerds who were fairly hostile at first into ones that learned to enjoy her music, with a few jokes to boot.
And with that Jessie was back on a 26-hour plane journey home to London (she was only in the country a day and a half).
